My suggestion is to leave her alone. I mean, no contact from you if it is not an extreme emergency! You need professional therapy before you can be the kind of H and father your family derserves. You need to work on yourself and completly renew the kind of man you've become. She can't return to the cr@p M she left, and who would blame her?
Look, I speak pretty bluntly and maybe that's why I post to more men than women, but mostly I post to the LBH's b/c I was a WAW. The worst thing for a WAW is the thought of continuing in a MR that brought her so much pain. So, that's why I telling you that she's has to see a total different picture! And......she won't trust it for quite a long time. So, get your focus on yourself and what you need to do to make life long changes. That have to stick!!!! She has to know you mean business by seeing for herself how much growth you acomplish. She isn't going to listen to your words.
Don't think of even trying to get her back at this point. Get help for yourself and focus on being good father.
Work toward only those things that you can change. You can't change the past or other people......only you and a shot at a better future.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
