So my husband and I officially separated a year ago after all the back and forth, between me and his current girlfriend.

We've tired to keep things friendly for our children's sake but maybe a little too friendly. He's been cheating on his girlfriend for the past 9 months with me.

A part of me wants to tell her but a part would rather let her find out. She didn't care the other 2 times I told her we were still sleeping together. I wanna feel bad but I can't. It's my husband who comes to me, it's not like I'm the one who's starting things. She should've known he would eventually cheat on her if he cheated on me with her. Any advice???

I know we should stop. I've told him no many times and stop letting him in my house but for some reason I always give in...
