I just dont know if im overreacting here. What do you think?

My boyfriend and I have been planning our wedding for two years. What were going yo wear. What guests will wear. What kind of wedding. What kind of reception. All of it. And we have always talked about doing it the way we planned. we never disagreed on any of it. And the theme itself was something that has been a huge part of us as a couple so it was meaningful to both of us. Well this morning he texts me saying hes not doing that anymore. He wants to do something completely different for himself(dress as billy joel). Billy joel had absolutelt nothing to do with us as a couple. I didnt even know he liked billy joel. And now all of a sudden he wants to dress up as him for our wedding. And i got super pissed because what the hell am i supposed to do then? He says im being controlling and trying to just make it about me...like nom it was about US and now you want to make it about YOU. Wtf? Im so pissed.

On top of this just a week ago he made plans to live on his own for another 6 months(were currently living in different states because were waiting for q new house to go through). So im here alone woth the baby qnd he made the decision without even talking ti me about it that he is going to stay where he is for at least 6 more months and save up money and start a career and all that and then i can move there when he has wnough saved....without even talking to me about it. He just made the decision and told me. We werent even planning on moving there until weve been in this new house for at least year so he can get his career established and then were going to move there wjen he can transfer. Thats been the plan since the begining of this year. So i got really pissed then too.

And now im feeling like hes doing all of these things that are like he's scremaing he wants to be single he just doesnt want to lose me. He likes being with me he just doesnt like having to do all thw things couples do. He wants it to be all about him. He wants to make all of the decisions by himself. he doesnt want to have to talk to me about anything. He doesnt want to share how he feels about things with me unless hes pissed. He wont talk to me about any problems we have.

So i told him im tired of trying ti be a couple with someone who wants nothing to do with actually being a couple. I told him maybe he should stop and think abour the real reason he wants to marry me and if he actually does because hes making it all about him and he makes it very clear that he doesnt want to have to deal with all of the major parts if being a couple.

Am i over reacting? Reading too much into it?
