I’m pregnant. He resents me. Advice please?! I feel terrible

I 19 recently found out I’m pregnant by 20 yo child’s father. To make a long story short, I met my child’s father off of a dating app and when we met up, we had sex and that’s the night I got pregnant. I’m now almost 2 months pregnant and I was completely honest with him and told him that I lied about being on birth control, he absolutely resents me for it. He’s such a sweet soul and he told me he doesn’t wanna be with me but whatever decision we decide that he would support it. He said he would be excited to be a father but that he isn’t ready and that he had dreams of college and football to pursue. That he was just about to go back to college. But he told me he wouldn’t be upset one bit if I kept it, but that his issues are with me, not the baby.

He’s been depressed these last couple of days, but his mother reached out to me and asked if I would come to dinner to talk this weekend. She also offered to take custody of the baby until we got our things together and we got stable. Over text, I took her up on the offer but she hasn’t responded as of yet.

We found out last week and we’ve been talking since, but today I called and he said he didn’t wanna talk about how he was feeling. He told me yesterday that lately he’s been crying and drinking heavy bc he feels like he had no choice in the matter. He told me he doesn’t trust me or believe a word I say.

Looking for advice. Should I leave him alone the remainder of my pregnancy? And just let him cope that way? I don’t know what to do.

Edit- I plan to change my number and leave he and his family alone. Would this be a bad idea? I don’t want him to be affected by my decisions and I feel terribly. I just want him to move on with his life and follow his dreams.
