Yes, people use people. MLCers use OM/OW. OM/OM come in several flavours. Several become manipulative, etc. because of the situation. Regardless, it was the MLCer that feed OM/OW with lies about the marriage and spouse.
It was the MLCer that was dying to have an affair. Lets stop pretend the MLCer is innocent and OM/OW are always an horrible person that made the MLCer had an affair, cheat, leave, tell OM/OW they didn't love their spouse, that the marriage was dead and so on.
A fully recoved would not be pointing fingers to the alienator nor to their LBS. A fully recoved MLCer would know it was on them. All of it.
SS's is recovering, but, as far as I am concerned, still has a long way to go to be fully recovered.
