Is my decision too harsh? Never telling my ex I had his baby

Long story short..

I dated a friend who was in the navy for 7 months. We live in different states so it was long distance. Through the relationship, he was always very loving and supportive- we talked every night. He came back home and acted different avoiding me and just doing his own thing. When I confronted him he said that because he was going to get deployed soon he wanted to focus on himself.

Heart broken I accepted his decision and wished him the best. 4 weeks later after we stopped talking I find out I’m pregnant.

I decided I’m never going to let him know or let him see the baby because I don’t want the drama. I don’t want my child to be told he’s unwanted and I don’t want my ex to hate me for carrying the pregnancy to term. This is a high risk pregnancy and I don’t want to stress myself out I feel like I’ve made my decision like he made his.

Our mutual friends feel like I should tell him but I already know his response- “ I don’t want kids& were not together “

Am I being selfish? Should I listen to them? I feel so stuck right now. I want to be a good mom and do what’s best for my baby. Please help!
