Traveling Without BF

My boyfriend and I have been together for over a year. We met after he moved here for graduate school. He's felt lonely out here even while dating me as he hasn't really tried to go out and make new connections and friends here. Early in our relationship, he moved back home only to move back here to try to really make our relationship work. Here is the problem: I recently made plans to go to a convention that my friends and I have been talking about going to for years. It is a great opportunity for me to network and drum up business for my website and to make business connections, not to mention the fun of the convention itself. When I bought the ticket, I made the mistake of not waiting to make sure my boyfriend could go with me. He was very upset at me because he couldn't go because of work and said he was angry that I didn't even ask him if it bothered him if I went without him. He made me angry when he said that if I went without him then it showed that I didn't care about the relationship enough and he should be rethinking moving out here in the first place. While I should have talked to him first, that comment felt manipulative and childish to me. I made sure to ask him if he meant it and he said he didn't, he was just feeling homesick. He made a good point about me needing to have asked him first and I apologized and we talked about it and he never said anything about how it would be a problem if I went after this conversation. However, since then I haven't been able to even mention the convention without him getting angry and depressed, so it has me thinking whether I should go at all. This is a huge event for me, my friends, and my work, and if I don't go I feel like I would be very angry at him for denying me this opportunity, however, I don't want to lose him because of this either. I would appreciate some advice, please.

You need to get your priorities straight and do what you want to do first before what he wants you to do. Being in a relationship is all about compromise this is a huge deal for you and you shouldn't pass up on it & he should support you 100% not moping around for him not being able to go with you. Talk to him about it again and tell him how you feel.
