I reckon that XW's FF is after you. I thought that the first time you posted about her and the more you write of her, the more I think so. She is hunting and you're the catch, that's why she is more willing to see your side of the M, asking for advice on her little problems (a woman's way of bonding is to talk), complimenting you etc.
It is blatently see-through, and if you are still interested in your XW, I would be very careful because you're not going to score points with her if you start getting involved with her best friend. I mean, that is a cardinal sin, along the same lines as me sleeping with Andy's brother.
Just be careful. I am a woman and I know when one is flirting.
