But isn't this a risk one takes anytime you have children married or unmarried. I mean really, do we ever really say, if my H and I end, I would want my child being around another woman.
The problem is the OW in our cases got involved with them BEFORE we ended our R. I see that as a huge difference b/w a woman that would date a man after D. From most of the postings here, and in my own case, the OP's are messed-up individuals, poor parents, etc.
You mention yourself as a single parent, but you won't be, your H will have an influence/control over your child, and if you break up, the OW may have also. I think you should continue praying and maybe IC about this also, and not just with your family members that can't be totally objective.
