"Going to NYC would be for ME, she could always join me later but would have to really want to work on M. I'm afraid though if I leave we'll never get it back."
I'm "afraid" if you DON'T leave, you'll never get it back.
SC, stop being "afraid." It's lame and women hate that sh!t. It makes you look weak and that is very unattractive.
Unfaithful women go batsh!t when they are dumped by their OM. So, start treating her the way OM eventually treat their affair partners. Reject her! Dump her @ss and go to NYC.
