Hey, it's OP here! Thank you for all the positive and supportive comments. Basically the story goes, we moved into a neighborhood a few months back, and our neighbor had been talking about needing some work done on her house because of lighting issued when we were all first introduced. I knew he dropped by once while I was at work to check out her lights, but he had never previously given me any reason not to trust him. So this came as a surprise to me when he revealed it to me, I guess he just somehow assumed I knew and I just didn't care. So yeah, there goes the end of a 3 year relationship. I guess all I can say now is good riddance to bad love.
