<human>: I have been dating this girl for a while now and everything is going well except for the fact she still talks to her ex. I am not sure what to make of it. They were separated for about 2 months and then he tried to start getting back with her. I was in the picture at this point and she told me she needed time to think. I wanted a relationship but she turned me down the first time because she was to confused.

So eventually I asked her again this time she said yes and we began being exclusive. however she still finds time to talk with her ex here and there during the week. since we started dating exclusively and said it was just meeting up to chat and what not. She refuses to talk with him on weekend as I have come to learn but will occasionally respond to his requests to hang out on week days. Who is in the wrong here? Is this relationship just a festering pimple ready to pop?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My gf of 8 months still occasionally hangs out with her ex on week days to catch up. Is this going to hurt our relationship long term?
