Question for single mothers -What should I do?

Recently I found out I am pregnant. Currently at 8 weeks. I told my family the news, but they kept asking to meet the guy. I told them they would eventually meet him, but we are not in a relationship right now. They keep pressing the situation to meet him & I'm not going to lie it’s making me a little bit uncomfortable. I know I’m having his baby, but we’re still figuring things out. My parents don’t know why I’m refusing to work things out with him. I don’t want to tell them why either.

Honestly, me and the guy barely knew each other and hooked up for a few days. During this time, we went out on a few dates & got to know each other. He asked me to be his girlfriend & I told him I needed more time to think about it… We had only been together for 4 days… next thing I knew he disappeared… When I texted him I was pregnant that’s when I found out he was still in a relationship with his BM. He has 2 kids by her that are 4 & 5. Keep in mind he told me he was single & my friend (who is his cousin) confirmed they had been broken up for over a year.

After finding out this was all a lie I was hurt and confused. I had asked my friend about it & he had no idea they were still together because he doesn’t talk about her & she hasn’t been around for a long time. Eventually, he’ll need to tell his girlfriend the truth. I feel like he’s being bogus to her by lying & sneaking off to talk to me. Part of me wants to tell her myself because if it were me I’d want to know! I feel like he’s being stupid and selfish. When the baby gets here like how do you expect to be a father without her knowing?? That makes me sick. I’m happy he wants to be a part of our baby’s life but frustrated with his actions.

This is why I don’t want to tell my parents or have him meet them yet.

Ik it’s a lot, but my parents really won’t leave this alone even after I told them we aren’t together. Idk what to do
