I don't know what to think

Ok so it's been 4 months since I last spoke to my cheating ex, Ive maintained a strict NC pattern in my life. Occasionally I used to have people ask me about her but I always brushed it off and said we were over and preferred not to talk about her ever again. Well over the weekend a friend of mine meets up with me at a bar where we are celebrating with some friends and asks me if I resumed contact with her. I responded with a hell no and asked her why and she said my ex had posted a photo of us on her facebook wall an she thought my ex and I were talking again or something. Initially I brushed it off thinking that was odd but it's slowly been eating at me. What is going through her head that she posted that, she is still with the guy she left me for I think. I really wish I hadn't heard of that photo but now that I know its there it's just eating at me piece by piece. As much as I will want to I won't contact her I know it's done but I wish I could just understand her reasoning, but then again knowing her there probably isn't one.
