I want to reiterate something Lou said to you. You were trying to "protect" someone....who is also cheating on her spouse. Perhaps yes, she's now cut things off....for now, but as you've stated yourself...she'll backoff...then come running back.
She's made her own choices in this A...it's up to her to protect herself...and extracate herself from her own mess.
I also agree with Lou in the fact that...if you wish to have support here...do it with the group, not one-on-one through e-mails...but lets be clear...no one is asking you to leave. I don't say that to have you thinking "great the people I viewed as friends are cutting me off.) That's not it at all....it's that if you limit yourself to posting here...and seeing your C/MC then WE can collectively support you much better than we could have done individually.
You also (as I've said numerous times to you before) have to go complete no contact with OW...period!
It's pretty much up to you. Do you want to fix this mess? Do you want to repair your M and make it better? If so do the work, be honest with yourself (and I mean really honest about what you've been doing)...stop wallowing in self-pity and DO SOMETHING ABOUT THIS.
