Yes. I had been in a relationship with 'Alice' for many years. After we broke up, I was a total mess. I still depended on her for emotional support, etc. For a while I called her often and she always picked up to be there for me. Eventually someone told me she had cheated on me when we were dating and being young and dumb that made me angry enough to stop calling/ leaning on her

Fast forward a few years and I have a new girlfriend 'Kate' for a year or so. I'm back home for a weekend while 'Kate' is away and run into 'Alice's' mom who had been like a mother to me for years. She says she's sad the two of us don't talk and says I should talk to 'Alice'.

I go to her place and we hang out. I come to find out that she hadn't cheated at all, but she let me think that so we could both move on. I learn that she was with a new guy while I was calling her all the time. One who went through her phone and beat the shit out of her every time I called. She wanted to be there for me enough to not tell me about it at the time. We laughed and cried and found ourselves hugging and yeah.

I told 'Kate' the next day. Turned out that she had stepped out as well since we were long distance and hadn't told me. I was pissed and we broke up... for about two weeks. We both realized we hated being apart more than we hated the idea of the other stepping out. We resolved to just be honest if we stepped out and deal with it. Got married a little over 10 years ago and could not be happier!
