I just wanted to reach out and send a hug! It has been a rough week for a lot of people I think. At least he went to MC. Sorry I try to see the positives in things.
You are the mother of your D. You have to make the decision that you feel is in her best interest. I haven't read your entire sitch so I'm sorry I can't offer more advice at this time.
Just know that we are all here for you and rooting for you. Work on yojrsrlf and know that whether this journey ends with or without your H you have been given a gift of being the best you that you can be. I personally feel that posting helps me. I don't know about you but me just typing things out helps relieve some stress or frustration. It also helps me from avoiding responding emotionally to H
Hugs!
And as far as if you would have done this or done that .. I still think that .. I still posted about it today. But hindsight is what it is. We can only change the future. Fix what YOU can fix now for you, to be a better W to either your H or your next relationship. And who knows - maybe if you did listen or did communicate better. Who is to say H wouldn't have had something else that bothered him? Playing devils advocate - don't beat yourself up. Own your faults and work on them for you
