maybe shes still messing around with the babys daddy. Who knows. But IMO i say just run with it. Be friends let it take it where it goes, IF she is ever ready for the relationship she will let you know. So don't push it. And what could be the worse thing that can happen.. you might just end up with a good friend.

And if she was already with you for a couple weeks then obviously she likes you, and who you are. having a child is hard work, and they demand a lot of attention especially if shes a single mother.
