YoYo...don't assume based on MIL conversation. She was hurt too, (you said H's father left the family) and may be assuming H will decide to leave based on that.

And doesn't it suck that since we are independent and strong, our H's think we can handle life alone? I know H told me that OW needs him, and I didn't - WTF! Which one of us is raising his kids??

Hang in there...in my case, a separation from my H was good to clear my head. You can stop focusing on where/what he's doing, and focus on what YOU are doing. It is easier for me when he is farther away. VJ
