I KNOW I can turn this around, unfortunately I don't WANT TO anymore.
It takes TWO people to make it work, not just one. I know DBing says for one person to work on themselves but it actually takes both to come to an amicable solution for the problems in the long-run. So if either of you isn't willing to put in the work for the M, then you have a huuuge uphill battle. And then the times comes when you say, Keep at it or move on? Sounds like you reached the end. Not saying that is good or bad but you have to do what is best for you.
