I guess I'm confused as to what I should be doing now, other than getting a life and moving forward on my own.

Do I stay dark with BF or be friends to be in his life, period?

ME: 38
BF: 40
T: 10y, no kids, no M (by choice)
BD: 7/14/14, BF admits to PA, wants out, lies about new R.
10/1/14: I move out, BF lies about move in with OW
12/4/14: OW confronted, reveals all the lies
