So, background, this is the age old story of H lying and cheating. After I caught him we agreed to give our marriage another go as we've 2 small children and then I found out he never gave up the OW. So now he's gone and I'm pretty sure he's moved in with her even though he says not. Of course I'm devastated but I don't want him back. This has all unfolded over the last 5 months - you've just got the very abridged version!
Throughout all this I have remained dignified, and civilised at all times. I promised myself that if nothing else I would be able to look back, hold my head up and say I did my best and I behaved well. We have managed to remain 'amicable' (starting to hate that word) mainly due to me doing everything I can to protect the kids. BUT I hate the thought the the OW having any kind of influence or part in my children's life. Apart from the fact that she clearly thinks sleeping with other people's husbands is acceptable I know enough about her to know that she is just not the kind of person I want them to be around. I know she did not break any promises, I know that my ex is the villain of the piece but frankly I'd like to break them up.
So I have 2 bits of information that could cause them difficulties. One is that he has joined an online dating site in the last 3 months and is active on it. This could be revealed by simply sending her a link to his profile anonymously. The second is that he went on a holiday with us while we were 'trying again' and I'm pretty sure he lied to her and told her he was away on a work trip at the time.
Do I surrender the moral high ground and act on this? I'm pretty sure I could do it without him finding out that I'm the source. I've got to the point that I think that the best revenge is that she gets to deal with his shit but I don't want her in my kids' lives.
