Don’t get me wrong, he (17M) doesn’t have to enjoy everything I (18F) like, but he always talks about how much he hates my stuff.
I don’t like his stuff all the time, I like reading and he doesn’t for example. However, he doesn’t like a lot of things, and a post reminded me of this. He has to complain about how he doesn’t like it and how he doesn’t wanna watch stuff with me and how he doesn’t like this stuff and how he’s 17, so he’s so mature and can’t watch my “kid stuff”.
I think it’s fine to have different interests in a relationship, but maybe you should have a conversation with him about how he communicates those opinions. It can be hurtful to hear someone you care about complain about your hobbies, even if he’s not doing so with the intention of hurting your feelings. Maturity involves respecting other people, and that includes allowing others to enjoy things without shaming them. That said, if you know he doesn’t like a lot of the same things as you, it’s probably better to focus on the interests that you know you have in common while probing out other compatible interests.
