"He cheats on me. I am OK with this as long as he doesn't leave me for good. It's better than getting a divorce."
It's been a few years, he hasn't recommitted. Not really. So ask yourself this, how much longer is this going to go on for? The answer is 'as long as you allow it'.
Do you not deserve better than a man who lies and cheats and doesn't treat you with respect? Or are you crossing your fingers, hoping for a miracle? Because it seems to me that you are, which is OK but again, how long will you hold out for miracle?
Puppy is right, if the only reason he comes back is that OW leaves him, there is no guarantee that he won't find another OW, or another OW get her clutches on HIM. He would not had to face the real issues of his R's and you are back where you started.
I am not saying that you should go ahead with the legal, there are other options. But I think if you REALLY ask him, for real, if he can actually commit again, then you will have an answer. And you know what, it might just kill the last bit of love you have for him and then you will be free and be able to move on without guilt or regrets. Then it WILL become what you want. As opposed to now, moving ahead, but not really meaning to. Does that make sense?
