<human>: I won't give too much of a story here, but basically my ex gf and I dated for over a year. During that time, she fell out of love and began to talk (ONLY talk) to another man. Our relationship clearly ended for the better. Now that we are starting to talk again (4 months have passed since breaking up), I feel like I need to tell her that while broken up, I had sex with another woman...or should I? I'm not here to have people tell me whether or not her and I should get back together, that's something I'll decide on my own if it feels right. I simply want advice on how to tell her I had sex with someone else while we weren't together. I know it wasn't technically wrong, but I know if she did the same thing while we were broken up, I would be upset and would want to know. My fear is, if I tell her the wrong way, she may run off and not want to give it another chance. I care deeply about my ex gf and the sex with another girl was just my poor attempt to move on.

Give me a shortened version of the text
<bot>: GF and I broke up. I had sex with someone else while we were broken up. Not sure how to tell GF (still not dating at the moment) about other girl.
