On the otherhand a lot of them may not understand what damage they are doing as they probably have never been in our shoes
This might be true as well. I think anyone that gets involved with a married person lacks morals. H's OW is married with two young kids the same age as mine, and it didn't stop her (being married). Who knows? I try HARD not to place my blame on OW. I chant in my head that my H owed his loyalty to me, that OW owes me nothing. Now, the loyalty she owes to her H and kids....that's another thing, something she has to answer to.
