I'm not divorced, and I've done a little bit of dating. I don't even think we have a waiting period here, but it's been over a year of ridiculousness dealing with this a-hole, and we are heading to trial in March. I'm not working off his timeline for when I date, I'm working off my personal healing and just waiting till I'm ready..
As far as the kids, there was one guy who was pretty good to me. We didn't see each other much as I almost always have the kids, but we were communicating pretty often for about 2 months when DS10 asked me who I was texting with. I told him there was a man I was talking to who was being very nice and sweet to mommy. He asked if he was a "boyfriend," and I told him, "No, we are just talking right now," but I asked DS10 if he would be okay if I did get a boyfriend, and he said, "Of course!"
I believe in being honest with children, telling them the truth, and then supporting them and ensuring them things will be okay.
I don't plan on springing a man on the kids out of nowhere, keeping him a secret until months later when we are serious. Pretty sure I will let the kids know slowly if I start developing a relationship. Not telling them too much of course, or taking them on a ride of ups and downs with different men, but just letting them know and supporting them along the way when they ask questions.
I agree your kid might not have needed the technical answers of married versus not married and that he probably just wanted assurance that you will not be prioritizing this woman over him as your wife has done with her OM. He's probably just scared he will lose you, so I think maybe you could have focused on your relationship with him rather than your relationship with the woman..
