I'm in love with someone who doesn't love me back. It's killing me. He tells me that he cares about me but he doesn't apologise when he upsets me. He's said some very hurtful things to me, to the point that I'm considering ending things with him but I'm grieving at the idea of not having him in my life. I love this man so much and I never thought I could feel this strongly before. I don't know if this is a BPD thing, but this is killing me. Even when he's right beside me I feel like he's so far away. He's the first person I've been in love with and the fact that he doesn't love me back is like a knife in my chest. 

I've been told that the answer is simple and just leave him if I'm not getting what I want out of the relationship, but just the thought of it being a real possibility just sends me into a panic. I feel like an obsessive stalker (I'm not a stalker) but I just can't bare losing him. If he can move on and I can't, then I'll be stuck in my mind of memories and spiral down.
