Boyfriend's Birthday

Amron
Well, my boyfriend's birthday passed. I had all this great stuff planned! To decorate the apartment and surprise him when he came home with a cake and his present and then taking him out to the city to look around and get a nice steak. 
He ended up coming back home after just leaving for work and said he just wanted to spend the rest of the day with me. So it kinda ruined my little surprise for him. 
I ended up just decorating the room and his cousin came over and we smoked a bit and played video games ( so lame, but that's what he wanted). And I gave him his present and then we cut the cake. 
I told him to start getting ready for dinner and he didn't want to. And I'm just like wtf! Everything I had planned he turned down and it was making me so mad! 
He ended up wanting Chinese take out so I eventually just got him that. 
Well, today his brother calls and says he wants to do a carne asada for him Sunday because he didn't get to do anything for him on the day of. And he was all gung ho about it... 
Side story: this is gonna be super weird but his brother was my moms fiancé. He ended up breaking up with her last year and it sucked. I still lived with him for a few months and it was miserable because he was so mean to me and ugly! So I ended up movin out when I had money saved and took his brother with me. As of late, we have been getting along only because I have to accept that they are family and I can't do anything about that.
So going back to that house where my mom and brother and step sister all lived as a family is so fkn weird. It hurts! I can't stand going there, I have to either be high or drunk, I can't deal with it. 
Anyway, I'm just feeling some type of way because my boyfriend seemed like he shot down all my plans and it sucked, it was a lame ass birthday and I know he knows it too! But he made it that way! 
I'm just all mixed up because I'm butthurt he didn't wanna do shit with me and wants to do this thing with his brother. And the fact that I still feel a bit uncomfortable at that old house and around his brother and new family....
I'm just venting and it really sucks.. I can't tell my boyfriend much because this is what I signed up for.
