Lostman, your sich sounds very similar to mine as well as the way you are responding.... I was in this sich 6 months ago but didn't pursue proof or the A, I spent 6 months trying to be the best H possible, begged, pleaded but the A and R kept coming up.
Finally I snooped and got proof of the A and she admitted 2 weeks ago, I should have set boundaries right there and then and didn't. She's moved out now and I'm trying my best to resist any contact, it's tough though - just yesterday she reached out wanting help for a job application at work and I reluctantly helped.
There are good days and bad days, yesterday was a bad day for me and I sought guidance here, in prayer and read the lighthouse story. Today is a better day but it can change any hour...
Keep working at it and set yourself some goals, I've found this very helpful for me.
