That's a shame!!! I just had an abortion 2 days ago...I was in a similar situation except unmarried and I wasn't with the guy as long. We got pregnant the 1st time by mistake, but I had a miscarriage. Then he asked me to try again. I agreed because I thought that we were going to be a family. After attending prenatal visits and an ultrasound, as well as announcing to our families that we were having a baby and going to get married next year, he decided that he didn't want to be with me anymore and that I should have an abortion to, "cut all ties." We are tied forever because we conceived 2 children together...anyhow, I was going to keep my baby at first, but after further attempts to talk to him, I realized that he would not be there for our baby at all...and I did not want to be a single mom...I already suffer from clinical depression and an anxiety disorder...the stress of the pregnancy was making both worse and I didn't want my baby to suffer from my issues...and I wanted my baby to be loved by BOTH parents.
I don't know if this was the best decision but I believe it was because of the circumstances...you sound like you want to keep your baby...if that's what you want, then keep it...you will regret it if you have an abortion and you're not 100% sure about it...I regret it because it was my baby, too...even though I believe it was the best decision...but if I wanted my baby as much as you seem to want yours, then I would have kept it.
