I (18f) ex bf (20) we had been together for 8 months. we broke up because of him being controlling and verbally, physically abusive. I had gotten pregnant in the last month that we were together without knowing. i found out i was pregnant 7 months later when i went to have lunch with my mom and she asked if i would take a pregnancy test because she felt something was off and sure enough it was positive. the next day i had my mom come with me to the obgyn clinic to find out how far along i was and ended up being 27 weeks. i had no idea due to the fact it was a cryptic pregnancy and i didn’t have a bump, no symptoms at all and was still getting my periods every month. i tried to talk to him and work things out with him before i told him but every time it always ended with us arguing and him threatening me. my son is now 3 months old and im starting to feel like a shitty person for not telling him. AITA?
