Mine, too, was a boomerang, clinger, then vanisher since the 2.5 year stage, so just an average MLCer by the sounds of it. Mine too claims we're negotiating his separation. It will be 3 years this month since he first brought us in front of a judge to get separation which is the first step towards a divorce in Italy. Not yet legally separated. I have to say that this is not the usual separation situation. It will be 4 years since BD for me in May so I know the 'no expectations' and I am quite comfortable with it now. I know it means nothing as far as reconciling, but it does mean something as far as what kind of a split up we have.
If they just wanted to be done with us because they are in love and have moved on, we would all be divorced immediately. I know that if I fall in love with someone else, the first thing I'll do is cut my H off immediately, however much it costs me financially. Right?
That's not to say that if some of you have H who did divorce you immediately, that you are not still looking at a MLC. Once of the many things I've learned from HS, is that there are many varieties of MLCers. Not getting divorced immediately is just one of the clues.
Right now my H is not contacting my S13 either. That means OW is with him. It's just something I've figured out over time. I have finally worked out that it's best to leave him be while he's under her influence. I do reach out now and again, every month/2months but if he doesn't answer, I leave it.
