No friends...?

I had some girl friends. One stopped picking up her phone. I still talk to one a lot but we don't hang out. Ther other one( was my best friend) called me to hang out one weekend because she was coming home from college and she never called. She knows I am always home because I have a one year old and I told her I was always home. That was in November. Christmas comes around and she still didn't call. My other friend comes over to get his hari braided and tells me that he sees her over her Ex boyfriends house( who was an ***hole to her for 3 years) everyday. So I haven't talked to her because I find that messed up. Now I don't really have any girlfriends and all my guy friends are the same as my husband's so I see them all the time but its not the same. And its not like I can walk up to a girl and ask her to be my best friend. I am adult now and they wouldprobabyl look at me funny. I really friendly and laid back but I have no friends. What should I do?
