<human>: Me and my ex had been dating for about 2 years. We were both in high school and this fall I went to college, but she was in high school so it became long distance. About November 2013, she starts hanging out a lot with one of her guy friends. They didn't do anything other than study and hang out for a while, but she eventually confided in him that she was going to break up with me because of distance. She told some of her female friends too, but he told this guy too.

The guy friend starts flirting with her, trying to make her special, etc.. she obliges. 

I still went to visit her every other week and things seem fine, until we break up. I was okay with the break-up, the distance was kind of hard to keep a relationship. But Reddit, was it okay for my girlfriend to be hanging out with this other guy at Starbucks and maybe even going to dinner with him while she was dating me? Is that considered as cheating? I don't see how she got over it so quick. Everything else is our relationship was bliss until a few months back.

Give me the gist of the text in a nutshell
<bot>: Not sure if ex-girlfriend cheated on me. Hung out on "play dates" with one of her friends, but while we were dating and hid it from me knowing it would make me mad.
