BRNR, Just wanted to add my sympathy for your situation. I know what you are going through and I understand how low this sort of stuff makes you feel.
It's so unfair; there seems to be little that you can do to stop the selfish ways of the mlc-er. They just don't care about anyone apart from themselves.
I don't want to hijack your thread, so won't give specifics here, but I'll post about similar things my X is doing after 3 &1/2 yrs... I feel like it never stops with these guys.
