I have just caught up on the last few days. Firstly I am sorry for your pain. Your love has been unwavering despite your situation. That is pure love. You felt it and gave it regardless. For me that makes you a good man.
Mu, if the rest of what I say appears harsh, know that I say it out of genuine care for you.
You are reeling and spinning. I can understand that, but it is not helping you. You are making all the rookie mistakes which is not good especially seeing how long you have been here. Begging and pleading NEVER work. Stop that immediately.
You need to refocus on you, your kids and your future. This is nit the time to make rash decisions.You need to get yourself to a better place mentally.PPlease hold off making big decisions.
I understand your heartbreak and despair. I truly do. But part of me us glad that your situation has changed. Like everyone else here I would have preferred the change to be the opposite. Why say this when you are down? It is not to add to your woes. But being inflicted to such ongoing treatment is not good for you. Now you can grow.Seize that chance. Again don't be rash. Take your time. I was always amazed how you readily were going to live that for another two years. By amazed I mean in a good way that you were without hesitation willing to do that.
Now you need to accept what has been evident for a long time.Your R with W is over. Your M is over. You need to accept that for your own sake. Mut' let her go. I am not saying burn your love or that it cannot be restored later. I am saying it cannot be restored NOW.
Seeing as I am being hard on you, I'll add something.II find it suspicious that W prolonges her stay away with her boss the same weekend she announces D. If she is cheating on you, I would prefer that to be the reason she tells kids about the D and not this bullshiit about how you were all those years ago. Do not buy into that. I don't want this to become your focus but I would look into it.
Best wishes mate. Breath make some short term goals and focus on that.
