Taking my ex back…

My kids father and I were together for 10 years, when we found out I was pregnant with my daughter he told me he didn’t want another child but we continued with the pregnancy. Well he ended up cheating on me and we separated for a year now. We still get along great we coparent pretty well and at the end of the day we would do anything for each other and our kids. Well he came to my house yesterday asking me if he could come home. Saying he misses being with me and living with our kids. He said a lot of other things in regard to us getting back together but I don’t know. I don’t know what to do. My heart is telling me to give him one last chance but my head is telling me I’m being stupid.

I guess my question is has anyone ever gone through something similar and have gotten back with their ex and it actually work out for the better? I just have so much faith that it could work out if we both really want it to and work at it. I just keep getting the backlash from friends and family telling me I’m being stupid.

I’m just so lost and confused.
