I have been in a relationship with my boyfriend  (M21) for just over 6 months now and he has been nothing but loving and supportive. He knows everything about my mental issues and my BPD. And again, he's been wonderful with it, but I can see it upsets him when I have a sudden depression in my mood. 

I've tried to explain that he's done nothing wrong. And that I am happy, I just... Idk, sometimes I feel like I'm missing a connection in my head and that I'm just broken.. and that's why I am the way I am. I hate seeing how hard it is on him because I know he feels helpless when I'm like this. He says I don't seem like me anymore. That I used to be happier with him and he's questioned whether or not I truly love him or perhaps it's just my BPD and fear of being alone that makes me stay. 

I have spoken to him a few times about this. But he says it makes him feel inadequate and that nothing he does is good enough for me. This upsets me more because I feel guilty for putting him through this. I feel guilty for being sad and it's making me feel worse. I also feel guilty because he's trying to deal with depression at the moment so he has more than enough on his plate and I feel like I just keep adding to his stress. 

We have had more bad days lately, which is unusual for us. And it's upsetting me because I feel responsible for it all...I just feel like I'm going to lose him because of this. I'm not really sure what the point of this way.. I guess I was just hoping for some insight as to how I can control my BPD more.
