OK, well, my advice still stands... You are WAY TOO VULNERABLE right now.

What he's doing is abusive. You will start to get ILL if you stay there exposed to that.

Get you and your two kids out of there... He will have to provide you some means of financial support. You can contact a lawyer about that.

Just accuse him of the affair, you don't need evidence. You said people are already gossiping anyways. Forget the evidence... It's fruitless... He will deny anything you produce...

What's more important is you getting out of a vulnerable situation being exposed to abuse like this...

This is very early on... So you have your health and are stable right now, but if you live there much longer it will start to wear on you. You don't want that.

Put an exposure script together as a start.

Love Hurts has some good ones in her thread.. I updated them a bit, you can find them there...

Right now you are in such a vulnerable position you need to get out... I am hoping HR will act against this affair when you report it... But you can't report it in your current living conditions... you are too vulnerable.

Focus on planning living separately... Right now that's the most important thing.
