Yep.. and in hindsight, he was full of projection, and I found out after the fact, that he had been for half of our brief relationship.. his grandmother told me that I should be thanking the woman he was messing around with..
And I was like for what exactly? My mind did most of that work, especially toward the last half of our relationship.
But as messed up as cheating is, this wasn't a mutual relationship by any means where he was concerned. The woman in this case, was a neighbor and his grandmother's BFF and she had been pursuing him since he was a kid and his grandmother had agreed to trying to set them up when he turned 18.. but that didn't happen, because when he turned 18, WE started dating.. so, although we had already broken up because of other issues, and I had already moved on, he was still trying to get back with me, and when she told me this, the first thing I did was go to a clinic with my husband (then-boyfriend) and get tested for AIDS.
Although, we had always used condoms, we still had a pregnancy scare, and I wasn't taking any chances.
In all truth, I was angrier about being subject to a condescendingly racist nurse, who was all but eager to tell me that it would be a good idea to use protection and not be so promiscuous like a lot of women "like me" were, and I told her that maybe she should save the lecture for the dude who cheated instead of the one who was faithful.. I told her that I had just found out that he had been cheating, and although we used protection, I wasn't leaving anything to chance.. especially with my new boyfriend.
