Sounds like u already know what to do..all the warning signs are there
..
I feel so confused he is very mean sometimes and when i get mad for something he gets even more mad he doesn't get it that im going through a lot of hormones changes n stress and just make sad knowing that I ready know he won't b in my future cuz he doesn't know what's to have a serious relationship n even though he is 28 he very inmature
if you feel he shouldn't be go with that. your instincts are usually right especially being pregnant. if you do put his name on you might regret it.
I didnt put my daughters father on birth certificate or give her his last name. And we were even dating lol.
Its your choice completely. Do what you think is best.
