What should I do

Daddy

Me and my girlfriend been together for almost 4 years I just turned 19 and she is 21 long story short I cheated on her last year February and I honestly regret it anyways she was on birth control almost all the relationship but when I cheated she stop taking them which I understand but she never told me and she got pregnant and I thought me and her was on the same page She told me and honestly I told her to get a abortion I know that sounds like an asshole but at that time I was still 18 an just got some freedom but I didn’t want to be one of those boyfriends and Force her to get an abortion that would eat me up inside but I want to come to a agreement me and her but I keep trying to talk to her but she would cry or just not want to talk about it and a lot of time past and now she can’t have an abortion she’s due in 3 week and I don’t know what to do she moved in with me and now all I hear is about the baby tbh I don’t know what to do I thought I want going to shrug it off and say that’s life but I been really depressed lately and been honestly sad about my son coming to the world
