Single Moms?? Advice...💔

I'm 19, and I'm having my first baby... the father of my baby (24 y/o) and I have been up and down for a few years now... and now I think its for sure over since we fought a week ago (because I caught him in a lie) and haven't talked since and pretty sure he's talking to one of his exes.. 😔 I love and care for him so much. I feel like moving on would be so much easier if I wasn't pregnant with his baby.. it hurts because I never wanted a broken family, I wish he'd change.. Any advice ladies..I don't want to put baby in a bunch of stress but this kills me..😔😔   Â
