I am diagnosed BP2 aswell and I could have written much of your post myself.

I love my boyfriend, but he could do better than a crazy chick. I dont understand his love for me. He is cuddly and extremely supportive, but I find I get annoyed at him for his childish things. He also likes attention and when Im feeling crappy and want to be alone, he misses me. Then I feel guilty cos I dont miss him. I feel like he deserves someone who could love him like he loves me. I do love him, really really do. But I feel like Im starting to drive him away with my negativity.
