<human>: I have been seeing exclusively this girl for a few months now. She constantly hangouts with her ex-boyfriend: They talk all day, hangout from going out drinking to sun bathing all the time. I have previously brought up that it bothered me but she insisted I did not need to be concerned she was done with him. She has always considered him one of her best friends (prior to them dating ... twice). I didn't push the issue because things were not that serous yet but now things are picking up. I feel like its the elephant in the room. How much should I be concerned? Female and Male perspectives please! Should I confront her and really push the issue? To be honest I don't think it will workout in my favor. Thanks for your input guys

Can you give me a shortened version of the text?
<bot>: Girl I am seeing constantly talks and hangs out with her ex boyfriend (two time ex). Need advice knowing what to do.
