Wow, I hadn't thought of that before Earnest! I had no idea if one wouldn't forgive the other, that things couldn't move on. I was under the impression that if one had cheated, than that was it - they were both free to move on. I'm in limbo myself, neither of us has cheated, though he left me and it's now 2yrs down the track
I also thought that even if you had 'the thought' of being with someone else, or hankering after someone other than your mate, that you could be disfellowshipped for that? Proving it would be hard though. In my case, the ex was kissing a girl straddling him, no panties on. His elders did not inform me, I found out a year later, by accident. So if it were true that one could be disfellowshipped for wanting someone else, then surely I would be scripturally free seeing as he'd actually kissed another.
A situation in my area had one 'brother' having cheated on his wife not once, but twice. She took him back the first time. Second time, she kicked him out. He was counselled, reproved and the elders told the wife that it was HER fault because she cannot expect him to reject the other woman's advances. The cheating was oral sex. Anyhow, she of course was ropeable, because she was being blamed for him not having any self control. Remember, this was the second time it had happened. The other woman told the elders she'd performed the act, she'd wanted it and it was her fault. Both of them were reproved, and sit together at meetings waiting for their upcoming marriage. I feel so sorry for his ex wife! (Btw, she told me this, I didn't hear from gossip).
