need advice

Cy

so kind of a long story but I'll try my best to be short.

so when me and my sons father found out we were pregnant we were happy but things changed from him coming around constantly every week to once a month to completely stopped coming around at all and always making excuses as to why he dont. he's 21 I'm 20 he's acting like a teenager who doesn't want the responsibility and its completely irritating so I asked him why he stopped and his answer was that his aunt is controlling him and telling him to stay in the house all day and can't leave but yet why is it all of a sudden an issue? like it doesn't make sense... so I flat out asked him is it his aunt or himself keeping him distant and his response was literally "who said anything about my aunt?" then he got defensive as anything and right there I knew i had my answer. so I told him If your not around now how you going to be around when Lucas (our son) gets here and he got defensive again and said he just will but I don't believe him. so I broke up with him and ever since he been acting suicidal saying he don't want to be here anymore but wants to stay for Lucas but he doesn't show he cares at all. he don't ask me how my appointments go, if Lucas is doing okay, or anything he went to only one appt and one ultrasound when I was 7 weeks now I'm 23 weeks and he makes no effort for anything.

what I'm asking from y'all is what should I do? should I go for custody and force him to pay child support or just let him be and get away with not doing anything for him. should i let him be there for the birth of his son and have him sign the birth certificate or not sign it? I'm a ftm an it hurts since we planned Lucas and now he wants to be a big ole baby over his responsibilities and is running away from his problems. 😢😓 but this is our son 💙 and I couldn't be more happy to be his mommy.
