Advice!/ confused!

So I’ve been dating my boyfriend for 2 years now! We use to date back in high school but went our separate ways. I didn’t want to settle at the time. Well Years later I got pregnant and ended up splitting up with the baby daddy to be on my own! Well my high school boyfriend just happen to come back into my life right before I was about to give birth. Wasn’t sure what to do I still had feeling for him! Now the baby is born and baby daddy isn’t in the picture and the high school boyfriend has been supporting us since the baby was born. I moved out my moms house and we got a house together. He wants to get married but not sure how to tell my family! He’s a sweet guy and willing to do everything for us but my family seems like their not happy for me and doesn’t want him around! The baby daddy was nothing. He had no life did drugs he was 30 years old still relying on his parents for everything. My parents say they like my high school boyfriend better then baby daddy but I’m not sure. I want to marry him but I don’t want to tell my parents nor have them at our wedding! What should I do?
