Oh, one other thing. Given SO was so worried about whether having sex was OK, the right thing to do, worried he'd taken advantage of you maybe, he probably has good reason for feeling like a sh*t for sleeping with you. That is, he is probably cheating on you physically. Of course, realize, that I have NO WAY of knowing this. But, his massive show of guilt is probably motivated by something you don't know that he thinks if you did know would prevent you from sleeping with him. Whether or not you sleep with him is your biz. Don't do it though if you feel used, but only when you choose to because it is what you want for whatever reason. Still, given he has moved out and has an R with someone else, you owe it to yourself and your children to practice safe sex. You might want to speak with a sex educator about this. I did and I was surprised about many things. For instance, a BJ poses a risk of AIDS. Using a condom does not protect you from herpes. Something like 1/5 of people have herpes but don't know it, etc... Maybe you know all this stuff. I didn't, having gotten married just prior to AIDS becoming something women knew they had to worry about.
