I think you are worth waaaaaaaaay more than him or her and you deserve way better than you are being treated and can find someone way better....and maybe SHOULD.
I believe you look sweet and way better than you give yourself credit for, you have amazing eyes, are wonderful to talk to, you actually have something to say. I believe you have a warmth neither one of them can begin to radiate themselves.
I like you so much. I am so concerned that you choose to be alone so much and chose this dingbat as your best friend and I don't want you to be alone. I know that you are most likely right in your assessment of what went on in your marriage.
What I say to help you comes from what I've read from you.
And I'm pretty sure that no matter how right you are that the way to save your marriage is the different path. Seeing it differently.
I don't think you 'SHOULD'. I just think you still have the chance if you want it, and if you do, you have to look at it and go about it differently. If you want him back, change your mind and actions about what you think you did and he did or didn't do.
If you want to move forward without him, keep on as you have been.
I'm proud of you and in your corner either way. And I'd choose YOU as my friend, not him or her.
