8 days no contact

I’m on 8th day of no contact and pregnant with my ex. I ended things 9 days ago and said I didn’t want a family with him due to his issues. He didn’t like that and got super nasty with me and I haven’t heard from him since. What’s more heartbreaking is he hasn’t even bothered to call me to check in or text, I know I’m the one who ended things but still, it’s not like this situation is as cut and dry as a normal break up. I just need to know he still cares
