Most Helpful Guy
Count your losses, move on, and work on consider what happened. He seemed pretty selfish. But, don't try to combine interests. You should have interests that you happen to share, but if he doesn't share other interests, get a friend to go with you. Don't be bummed if he doesn't want to do SOME things with you. If he doesn't want to do anything except eat, have sex and watch tv together, I hate to say it, but he's not as in love with you as you are with him. If this was your only issue and he was this upset, he may have other issues with you, or he has another love interest, he doesn't want a relationship, or he took an issue like that way too seriously. And you know what, he didn't take your feelings into consideration it seems. At least for now, doesn't have to be forever, walk away, improve your own life, and try to be on the outside looking in. Is it healthy for that girl and that guy to be together? What do they have to do? Is it worth it? Figure that out and go from there, and if you go to start the relationship again, don't put all your eggs in that basket. Keep one foot out the door, ready to run for it.

He doesn't sound stubborn, he sounds selfish. I'd cut your losses and move on and I think deep down, you know this is the right thing to do. He doesn't truly cherish you if he won't even go to a museum with you to make you happy. You deserve better :)
