dating a woman who is obviously cheating on you with multiple people

who has 2 kids that aren't yours

with a baby daddy in prison

I mean, have some self respect my guy. If you really think the best you can do is going for a single mom that abuses you in order to take care of her kids and provide comfort while she goes around fucking everyone behind your back (and not really caring if you find out), then by all means go work things out with her. You'd deserve each other.

But if you want something better, remove yourself from this situation immediately. Go no contact with her and her kids, separate all social and financial ties, and start working on yourself.
