SBH - so sorry, I lost track of your thread after that last visit.
Some things for you to ponder: 1) IF you are planning on staying for the sake of the children, then you need to find a way to forgive her - for YOUR sake - and move forward.
2) IF you really cannot take living with your W any longer - I cannot lay any blame at your feet. You've tried extraordinarily hard. I'm living in reconciliation with my H after a very brief affair he had, nothing like what most of you have had to endure, and he has come back to me in all ways and made everything up to me, and it's been 3 years - and frankly, it is STILL hard some days. I've been having flashbacks during the holidays, I have to really work at this still sometimes.
What is your wife currently doing to make you feel loved? How is she doing at meeting your needs? Has she gotten the help that she needs? Maybe you are feeling this frustrated because she really isn't doing what is required to repair this relationship?
