I think it's all about the guy. I'm sure you know a lot of guys you might have thought to date, but now with kids, you realize for one reason or another, he's not the one. It's not just about you anymore.
I am the mother of a very busy 2 1/2 year old. I met my boyfriend at work. I was very apprehensive about dating (especially him meeting my daughter). But after we were talking for a while, we went on our first date. He came to my house and met my daughter right then. It wasn't something I would have done (had I over analzed the decision), but it felt right. My daughter loves him (and he adores her).
