Having the same interest in films, music, art, and literature isn’t one of the signs of a good relationship early on; it doesn’t guarantee a wholesome and sustainable relationship for the long term. Your relationship need not be perfect, but it HAS to be satisfying, happy and entail healthy relationship boundaries. And for that to happen, you need to say the magic words “I l love you”, and “I am sorry” when needed. You need to give each other space so that your individualities thrive; you need to be on the same page regarding the partaking of intimacy, and financial responsibilities.
