OK I need honest, and upfront answers regarding this:
My girlfriend has continued to have contact with her ex behind my back. Mails, FB chats, phone calls, small coffees, etc. Without me knowing about it or she ever thinking of maybe telling me...
Somehow in an argument this guy´s name came up. I ask her: "who the hell is he..." She tells me several times: "it is a friend, nothing to worry about..." I feel something is wrong and I keep pushing, and after a while she tells me, "well that guy is my ex, but he is just a friend nothing to worry about..."
I asked her if at any point the last months she ever felt the need to tell me she is still seeing him... She tells me: "you never asked about him... and I did nothing that would upset or hurt you..."
But at the same time she did asks me several times about all the women around me... But hey, she just asked me if they ever meant anything to me... But she never asked me if I had sex with them...

Please elaborate... WTF should I do? Who is right?
