You are right. I have done little actual work for the last 4 weeks, completely stressed over this, staring a hole in the screen, not wanting to make the wrong moves or anything to push her out. I have worshipped this woman for 17 years and I know she is making a big mistake, but she just can't see it. Claims the other guy and his kids need her too. He's a big liar and I have proven that to her, but she doesn't flinch.
I have asked her about if the shoe was on other foot (she was married once before me to an abusive cheater), and she says due to that relationship, she would have kicked me out the day she found out. With kids involved... I don't want to look like the one that made her leave in their eyes. I feel like she is looking for that to dump on me and so far she can't. I want to maintain some stability for their sake. She claims she is taking them when she goes, but not if I can stop it.
Its not that I can't stand up to her, I have many many times, but this is playing with fire here and a lot is on the line. The MC lead me to this site and the DR book but warned me there are no clear and easy answers to this. She advised me to continue doing as I have been.
