It sort of happened organically. Our oldest ...... figured it out around 15 on his own. He reached the age where he was old enough to figure out why men stopped by all the time and then began to wonder if I was his father. He wasn't upset that I wasn't his father as much as he was that his ...... was constantly ...... with other men. Once he and I talked and I explained that she wasn't cheating on me when she got pregnant, he sort of let it go, although it wasn't until about 8 years later that he really moved beyond it.
Our ...... found out because the older ...... told her. She wasn't upset at all. She and I always had a really close relationship and I was always daddy and still am.
The younger ...... figured it out mostly on his own around age 11. Like his sister, he wasn't bothered by it at all. He saw me as dad and that was that.
