The girl that I'm seeing still meets her ex-boyfriend ('Joe') now and again. I have no reason to suspect anything more than just two people who were very close, and who still spend a few hours together. She seems to always let me know that she's going to go and do such and such with 'Joe'. The only thing thats a little bid odd is that she hasn't actually told me thats it's her ex. If the situation was reversed, I could think of quite a few reasons as to why I'd not want to tell my current partner that the person that I was spending time with was my ex.
The weird thing is, it doesn't bother me. What I would like to get some input on is: Am I supposed to be bothered by her not telling me thats this guy was her ex? or that she still sees him?
