<human>: A little back story, I've known this girl for a while, our parents are best friends and me and her are close. We tried dating for a while but had to move a few hours away and it just didn't really work. We both regretted ending the relationship though. And have stayed good friends. 

A little while later she gets engaged, but then the engagement ends, and then we start talking about our relationship and how we both felt bad, and we almost started dating again to give it another try, which would have been fantastic. But then a couple weeks later she finds out she's pregnant with her ex's child. So would it be weird for me to date her or should we just stay friends? 

Oh and I've done the whole being like a father in a past relationship, and I loved that more than the relationship I was in with the mother, so raising a child isn't an issue, some might say I'm to young but it doesn't bother me. I have some experience in the matter
