<human>: Can you provide a brief overview of the text?

Sorry, for poor writing skills.

Me and my family moved from Ireland to the US when I was 16 and when we did I met a nice guy. He went to the same school and we got to know each other very well.

After 2 years of dating I ended up pregnant with a baby girl, I didn't have the heart to abort or give it up. He was a really good boyfriend to me during this time he got a really well paying job and worked his ass off.

We were a good couple until last year he left me for another woman, but he was still active in his daughters life. I was devesated I cried every single day because I couldn't believe he would do that to me.

He broke up with her 2 months after he left me and tried to win me back saying it was a mistake. I'm not sure what to do, I do still love him but I'm scared he'll hurt me again.

He said he still loves me and that he will do anything to get me back and wants to be a family. He's taken me on a few dates and even did something for me on mother's day and he really seems to be trying.

Should I give him another chance or just pull away.
<bot>: my (ex) boyfriend left me once for another woman but now he wants me back and I'm not sure what to do.
