H and I are separated as well, but LRT would be the technique I would use to save myself, but not necessarily my marriage in my case. Would you be willing to write a background of you marriage, how you guys resolved conflict, if you did at all, power struggles, problems etc?
A fuller picture may help you see where you can improve yourself. A common saying is become the woman only a fool would leave. It requires you to change many behaviours, take a good hard look at yourself and realize that this may take much longer than you ever thought (6 month mark for me and I am a baby compared to some).
In my case, I have always been the strong one in marriage, very controlling. My 180, even though we are separated has been to cede control of everyone except myself and to admit that weakness is okay. I did that by admitting I was wrong and that I loved H, even though he is with another woman right now. But those are my 180s and not yours.
If you post a little more background, maybe you can figure out a plan
