i bet you £10
I'll see that and raise it €100.
Sorry laura but he's full of BS in my humble opinion.
will try to stop things & tell him to get a god damn divorce!
Congratulations, you've just conditioned yourself to fail. Try implies that you'll have a go, but you already know that you won't be successful. If you really mean it, don't try, do.
"I will tell him we have to stop and that he has to get a god damn divorce before he gets into my bed again. It is only fair to his wife and also to me!"
Otherwise, he's going to carry on using you, just like he is carrying on betraying his wife's trust everytime he is with you.
