I think had I found this place post BD... My posts would have shown that before W moved out... We too had very little interaction and like you I was still scrambling looking for ways to fix things... As I've said before ... I would run myself ragged cleaning thinking that would make her happy... In my sitch the truth was , there was nothing I could do, she was miserable and she thought she found happiness elsewhere and at that time I was in the way between her and happiness ..... Was that really the case no... But in her mind it was so the separation had to happen, she had to take that road and learn without my help that there were things that were not my fault. As painful as it was even the A taught her that she in fact had some issues that had nothing to do with me ... Though she blamed me for years about those things
It's a tough time of year to be going through what you are going through. Been there done that .... My advice ... Do not allow this to define you. STOP rescuing her (taking care of her when she gets plowed) ... As painful as it is you must let her hit bottom and learn the lessons she needs to learn without you helping or even being remotely close .... DO NOT fill her needs, she fired you. You have to rebuild yourself now... There is damage caused by this, damage she is not going to be able to help you with... You owe it to your kids to become the strongest man they will ever know. Do not share with them the sitch, to young for that kind of talk... Just become the best man you can be... Let your W go and focus on you, you will need to use all the energy you have left to build a better you because using it on her at this point is a total waste of resources
Hang in there ... You are at a better point now than I was at this time
