I’ve been engaged for a little while now, but I don’t know why. 
I struggle with bpd so I have it stuck in my brain that I am the only person allowed to be in his life. 
That’s including his kid, mother, anyone. I just can’t stand. He knows all this. I was completely honest with him from the jump and he knows exactly how I feel and even moved states away from them all. 
But still I’m sitting here wondering why is he staying with me. No normal person would.
