so, it sounds as if pulling back and having less contact caused him to move towards you. What do you think about doing that again, but keeping distant until he actually makes the changes necessary and ditches OW? I know you've been doing that anyway, but it's the only thing I can think of..... The only other thing that comes to mind is the MLC timeline being impossible to influence, although I don't think that's particularly useful in terms of practicality of things to try
*sigh* Maybe if he was suspicious that someone else was on the scene (there doesn't have to be- just a bit of mystery?) it might provoke a thought that he might lose you? (Not that it's worked for me )
