Meet friends when I visit NYC

I'm a 39 year old single mom from FL who visited NYC for the 1st time in March and have fallen in love with the city I've been two other times since then and have another quick trip planned in Dec. I'd love to make some friends who live there who I can meet for lunch, dinner, a Broadway show,ect. when I visit. It'd be nice to see a familar face when I visit, especially someone who knows what their doing in the city (I have no clue what to do there in the winer)...lol. I'd like to e-mail, text, facebook, whatever to get to know some people before my next trip.
