Important facts: We aren't married but have been together 10 years and have 2 children, 5 and 9. About 7 years ago we separated for multiple months and both were with other people. We eventually worked things out, and things were great until a month ago.

We spent 2 years living out of our car and finally got our own house last December. She stuck around the entire time we were homeless. But now after being in our house for less than a year, she is having a long distance relationship and we're separated but living together. Her reason is that I took her for granted and she had been asking for help for months. There's some truth to that, I didn't realize the severity of things. But we were still fine until she started talking to an old friend of hers.

Now she says she's afraid to give us another chance because things won't improve. We've went back and forth on this. But she calls her bf every night for multiple hours, and I lose my mind and go completely crazy while she's on the phone with him. This resets any progress we make.

Help me fix my relationship. I'm not interested in hearing we're doomed and to accept it. I need a fighting chance. She can't move our kids out of state without a courts permission and refuses to move out of state and leave the kids with me. Effectively we're living together and I have no choice but to endure her other relationship. She says with time apart maybe we could work on things. But I don't know if I should just let her take the kids, or fight for them to stay here. (They want to stay here). She has no job, no income, no home; she would be moving in with her mom. I have a good feeling she won't like living in her old home town, as she never has. Do I let her leave and allow her to remember she hates it there, or do I fight for her to stay here and hope her long distance relationship fades?

The guy she's talking to is a smooth talker, but can't provide much for her financially. She's enjoyed staying home and homeschooling our kids. If she moves out she will have to get a job.

Any advice?
