He placed his trust in you. Women do not choose for the future, they choose for the comfort. Men, choose for the future, and they place the most trust you can imagine in their wives.
That trust is broken and you’ve lost it.
Sorry to tell you this, but you started out with problems, you fought all the time until you gave up on winning, then you went to someone else. You’ve already left, and while he MAY choose to take you back, will you respect him for it if he does?
If you do get back together. Take this advice. Sit down with him and design the marriage on paper. I mean really work at it. You need to set the style of marriage… is it going to be service, or money, or isolation, or what… then set the long term goal. House on the Beach, cabin in the woods, working in a garden together? It needs to be what you want to do when you retire. End goals. If you get that far, then set the power structure of the marriage. Who is in charge of what, when, and how. Lastly, set the terms of divorce. When you’re done, put it on paper. Read it aloud to at least two people you know. Make it a party.
IF you do that, then there’s a very good chance you’ll make it. Don’t, and I don’t hold out much hope.
