Why is it so hard for him to see where I’m coming from and put himself in my shoes?

Right now I’m on a break from someone that I have been with for going on two years now. I endured a lot of physical and verbal and amoroso abuse. I’ve left many times and have always came back. I never told authorities and I still speak to him after forgiving him yet again but this time It’s only conversation. I’m trying to stay away from him physically because I know I need to heal and get better and you can’t heal around the same person that hurt you. It makes it harder and tempts you way too much especially considering I still love him. This can be his time to get the help he needs too but he just keeps trying to make me feel bad for staying away. Or keep trying and trying to do and say anything to get me to break and to come around him despite me telling him as much as I want to be around him, create better memories for us and the relationship, the bad memories overtake me when I’m not around him so it’s worse when I am around him. He’s been saying that I don’t care about his feelings because if I did I would consider the fact that he understands I need to heal away from him but I should understand that he can’t go long without seeing me. He says it he misses me and overthinks when I’m not around him. In other words, he’s basically asking “How am suppose to feel about you choosing to stay away in order to heal?” He even said that it couldn’t be affecting me too bad because I’m still going on with my day to day life but for him to say that and to still say “I understand” makes me feel like he doesn’t really understand or want to understand like he’s saying.
