But that would make you a victim and you aren't - you're a strong woman, under a lot of emotional pressure yes, but not a victim.
Believe me, you couldn't be a confidant for your h, if you think you feel emotional now you wait till he starts spouting about his woes. I tried it, it doesn't work and the emotional toll on you is too great.
I know it seems counter-intuitive, but this is the best way. I did it the other way (begged, pleaded, bargained, took crumbs for 6 months) and look at the length of time in my position. It doesn't work.
