Does this sound hateful? (Breaking up)

I don’t know how to really break up with anyone. But I’m just really not happy in my current relationship. I’m on the spectrum and feel like I need this to be proofread before I send it. Sorry I just have no idea what I’m doing:( Today this guy was acting weird and I just don’t want to be with him anymore... and I keep trying to break up with him and he guilt trips me into staying... or he comes over and refuses to leave. Or calls me on burn numbers. or telling me I’m hurting my son by leaving him because he says my son is attached to him. (we been together only 5 months and my son is a year old- I don’t think he’s going to remember much. This is what I have so far...

“So, I’ve been thinking... I think I’ve might’ve hurt you a lot emotionally the last few weeks. And it’s not fair to you that you are trying your best and I keep doing this. I’ve got a lot going on and a lot I’m dealing with, and honestly I feel like I’m emotionally not available to be in a relationship like I thought I was. I can’t force it. You can’t force it. It’s not fair to either of us. I think you deserve someone who can show you the affection and love you deserve, because you are a great guy. Just, this isn’t working out for me. It’s too much stress and more than I can handle right now. I’m so sorry. But I think it’s best we go our separate ways starting now. Don’t call. Don’t text. Don’t come over. This hurts but it’s better than going through this all over and over again. I don’t know if I’ll ever be over Nick. I know what all I’ve said and agreed to work things out, but sometimes it just doesn’t work and I’ve got too much on my plate right now to deal with this. I’m so sorry.”

**i can’t do it face to face. (My last relationship I ended up with a sprained ankle after trying to leave and I’m just not comfortable doing that face to face for fear of that happening again. and having Asperger’s it’s really hard to do that over the phone because I freeze up and can’t communicate clearly plus I tried before and he just kept making excuses and whatnot and he kept calling when I did hang up. What do I do when he won’t let me off the phone? Or keeps calling? )
