Ok so maybe I'm being a bit paranoid here, or maybe DH is playing pointless mind games. Things have been a little strained recently, nothing we have not come out from before but yesterday after browsing FB, it came to my attention that DH has accepted a Friends Request from his ex. The reason this is bothering me is that he has always maintained that in the 14 years we have been together, married for 11 with a 4 year of DS, he has hated her guts. She left after numerous affairs, married someone she worked with and took their son with her. She treated him like s**t but for the sake of their DS DH has maintained some form of contact with her, which I have never had a problem with. However, a few months ago DH got a phone call from her saying that she was getting divorced, apparently she was very tearful down the phone etc etc and asking for his advice, he seemed to take great delight in telling me this, at the time I thought he was pleased as he was feeling a sense of what goes round comes round' but now I'm not so sure. I have not mentioned that I know they have been in contact via FB and am not too sure if or how I should approach this, or just let sleeping dogs lie, I'm really feeling very unsettled.
