This is confusing as you've got two threads atm.
Read the other one and I've seen others from you.
Your latest obsession seems to be that you're a 'good' person who did a bad thing.
But as your other thread shows, that's not true is it?
Someone who has an affair with a MM and cheats on her own husband doesn't suddenly turn overnight into the sort of person who can do that. There have to be layers of selfishness and attitudes to allow that to happen.
The other thread's a long one, but on it we can see that you were economical with the truth despite some posters spending ages trying to help you and the latest posts really do expose your true character as perhaps being a 'bad person doing yet more bad things'.
Your OM has now told his wife he's leaving, but is omitting to tell his wife about his affair with you.
Now he's said he's leaving his wife, you've run for the hills and started sniping about his wife!
And say that you intend to continue lying through your teeth to your husband.
Read a book that will reassure you that you're a good person who did a bad thing, but you're fooling no-one here......
