Oh man, I'm sorry

I'm that way with my boyfriend sometimes. I've actually been wanting to write a thread about it. I get so angry when my boyfriend tells me he doesn't want to have sex... no matter what the reason is. As soon as he turns my proposition down my mind immediately jumps into rejection mode - which harbors a cluster fuck of self centered, insecure thoughts. He must not be attracted to me, he's interested in someone else, I'm bad in bed, he doesn't love me... it's just ridiculous. And the worst part is I can sit here and tell you how ridiculous I know it is and yet I'll do it again the next time he says no.
He recently confronted me about this issue, and I apologized for my behavior, but I turned around and did it again tonight!
He asked for a massage, put on an amazing play list (all of the songs were ones we've listened to while having sex before), and laid down in bed. 9 times out of 10 a massage leads to sex for us. So with that in mind, plus the playlist going in the background, I totally thought it was sexy time. I was wrong, and when he affirmed that he wasn't interested I got pissed off and took my pillow to sleep on the couch. What the hell is my problem? Any insight would be much appreciated. I've been hesitant to initiate sex with him lately because I'm so afraid he'll say no and this whole crazy rejection induced bitch fest will start again.
I apologize for hijacking your thread OP. I just had to get that out. I hope your girlfriend comes around soon.
