You do not have to take it any futher. Remember she is your friend not "JUST a friend"
I would say that right now you need your friends. Not another relationship. Get your head screwed on straight and get yourself to a point where your happiness comes from within. If something develops out of that. Then let it if its what you choose. Just becareful around your daughter. I am sure she is confused enough as it is.

Make sure that friends of friends can see pictures
