Need advice for a WW who left

[dwh15]

Also, I realize nobody can make guarantees, but in general, what is the course of these affairs? Does a WW ever actually stick around and form a long term R with the OM? Or do they tend to fall apart after a few months? In my case, WW has only known OM a total of around 7 months and only been romantic around 4, but she's already living with him, shared bank account, and in general acting like an old married couple who's known each other for years. It has all the classic signs of a rebound, so I'm thinking it's definitely got a limited shelf life, but curious what other experiences around here were like. The 1st A partner lasted around 18 months before WW kicked him to the curb. Somehow she finally woke up to the fact that he was a bum and never going to hold a regular job - she got sick of supporting him. Current guy is working full time at least, but I know they've already had a couple of major blowouts and she was on the verge of leaving him not too long ago. Doesn't seem to bode well for the future.

Now I realize even if it falls apart with current guy, that doesn't mean anything, as there's a good chance she just finds a new guy and starts the process all over again. But I am curious if anyone has a general idea how these things tend to go. I'm assuming that if she ever breaks it off with current OM and is actually single, that would be the time to try and start rebuilding some sort of R between us. I think if I find out she's in the sack with yet another guy, I'm done for good. I don't plan on waiting around forever while she destroys her life.
