(Everyone please keep in mind I’m an actual person so please don’t be too harsh)

So I’ve been seeing this guy for 2 years(he’s married-and yes i knew from the jump,ik it’s a terrible decision). Well about 2 weeks ago i broke it off with him because I’m just trying to get my life together n stuff like that,just to find out yesterday that I’m pregnant 😞. I seriously don’t know what to do. I don’t wanna have an abortion because I’ve already been through that 2 years ago and i still haven’t recovered emotionally,also I’m only 22,i don’t wanna ruin myself. But on the other hand i don’t know if i wanna bring a child into this messy situation. And he has 2 daughters who are 13 & 14, i don’t wanna be the reason they look at him differently. He’s 39 btw. This entire situation has been giving me a headache, I’m just so lost because i feel like whatever decision i make, it’s not gonna end good. I’m looking for advice from someone older or some1 who may have been in a situation like this. Please don’t judge me i know i put myself in this situation!!
