how long do casual relationships last

How long do casual relationships last? I was compelled to think about this right in the middle of my first casual relationship. All I knew was that I felt good with him and just went along with it. He was in the same class as me. We started talking, and slowly, it evolved into a sexual relationship. He made it clear that what we had was casual but after a while, things got complicated. And that’s when I thought, “How long do casual relationships last? What am I allowed to feel for him? What are the rules?”

Romance and relationships work differently for the younger millennials and Gen Z. Sure, there are many picture-perfect couples so in love with each other that it can get nauseating (but in a good way), but casual relationships have become a prevalent trend nowadays and we are here to decode them for you!

What Is A Casual Relationship? 

Defining a casual relationship is no easy task. It could be a fling. Could be a friends-with-benefits relationship. Could even be a long-term casual relationship (surprise! It exists). Or it could be just a hookup. At the base of it all, a casual relationship is everything that is the opposite of a traditional, exclusive, committed relationship. Casual relationships are where you can have sex with your partner while maintaining light intimacy without having to go into a long-term commitment. 

There are several types of casual relationships. We have hookups i.e. uncommitted sexual encounters. There are FWBs i.e. friends-with-benefits wherein you have sexual relations with a friend without romantic commitment. One-night stands are when you have sex with a random stranger (or even a friend/acquaintance sometimes), never to be repeated again. And then there is the concept of booty calls and f*ck buddies wherein you’re regularly hooking up with someone without the added stress of commitment and intimacy.

What to expect in a casual relationship? 

It turns out that casual relationships are pretty typical. 18.6% of male college students and 7.4% of female college students reported having casual sex in the month prior to the study, according to The Journal of Sex Research. According to peer-reviewed studies on the same topic, 82% of men and 57% of women expressed gratitude for having a casual hookup or sexual experience, according to this article by the American Psychological Association. It usually develops into a casual dating relationship when these encounters with the same person become routine and you also engage in non-sexual activities together.

However, if this is your first time in such a situation and  you aren’t sure what to expect in a casual relationship, there are a few points to keep in mind:

  • Have realistic expectations: Don’t expect any more than the other person is ready to give. If you get into a casual relationship looking for commitment, you are bound to get disappointed
  • Be transparent: Make sure both of you know what the relationship will give to each of you
  • Define the rules: Decide whether it’s an open relationship or if you’d like it to be monogamous
  • Keep jealousy in check: If you want to keep things casual with a person, don’t try to lay your claim on them
  • Decide frequency and type of contact: Will it be once a week or more? Will you meet apart from hooking up? What activities are you allowed to do together?

If you’re looking to date a guy casually, you might wonder: Why do guys want casual relationships? Casual relationships do help keep emotional distance while having fun. And that’s exactly why some guys want them.

But this also brings up queries like: How long do casual relationships last? Do casual relationships ever turn serious? What should I expect in a casual relationship? This is what we will cover in the next part of this piece.

How Long Do Casual Relationships Last?  

A casual relationship can turn into a serious relationship, it can be one of the early stages in a relationship, or it can fizzle out without any explanation. But the reasons that people get into casual relationships are usually varied and subjective, which then skews the answer to the question: How long do casual relationships last?

A 2013 study into casual relationships showed that emerging adults, usually within the age gap of 18–29, engage mostly in casual relationships. Since this is an important period for the development of romantic bonds, this is typically when people get into hookups, FWBs, one-night stands, and casual uncommitted relationships with friends, acquaintances, or random strangers. 

“My college life was a non-stop list of hookups. It was a phase where I didn’t have to, nor did I want to, focus on a serious commitment. I just wanted to have fun. And I did! I never stopped to ask myself, how long do casual relationships last? Because whenever one relationship got over, I was already onto another. I think the duration can only be decided by the people involved and no one else,” says Helena, one of our readers from Chicago.

3. Are you capable of handling this without falling for them?

What if you want to end a casual relationship because you want more? Yep, that can happen. This kind of setup will result in tears if you’re someone who readily gets attached or catches feelings rapidly after hooking up.

Knowing oneself is the first rule of how to be in a casual relationship without being harmed. Go for it if you’re confident you can handle it and if you know that romantic emotions won’t play a role. Approach with extreme caution if you are uncertain.

4. Don’t mix your friend circles

Keep everything separate and never introduce this person to your regular group of friends. When things come to an end, it will invariably be messy and challenging if you have mutual friends. You can prevent this person from becoming a significant part of your life by having a separate outlet for yourself, like your friend circle.

“Trina, Michael, Lexi, and I have been friends since kindergarten,” shares Alicia, a 19-year-old college student. “When Michael and Lexi started an FWB kind of situation in high school, they told no one. Senior year of high school, both of them broke up, and now our group is gone. I haven’t seen Michael in months because of how Lexi would feel. It’s terrible.”

5. Know your boundaries and leave if you catch feelings

Know when to leave a toxic relationship and be honest with yourself about it. Most casual relationships work out well initially. Then they naturally run out of steam or someone leaves because they start to feel romantically toward the other. A casual relationship rarely develops into a long-lasting love affair. Although not impossible, clinging to such a notion would be extremely risky. Do yourself a favor and quit while you’re ahead if you begin to feel the emotional bubble.
