Thanks for stopping in on my thread. It is certainly bizarre when WAS starts peeking out of the tunnel. I see you are a few months behind me. My WAW/MLC has also begun showing signs of who she was starting about 3 or 4 months ago, but they are very scattered and sporadic.
About two weeks ago, there was a ten minute conversation that W initiated that made me feel like we were back about 3-4 years ago. It was great, but very brief before W reverted and withdrew.
After reading so much here about MLC and crises and WASes, I believe that there is truth to what is written here. Learning to let go is a very challenging thing to do, but at least as far as i can see, it is the only thing that works.
It is nice to see these touch and gos - but very important not to pursue. That's pressure.
My advice is the same I would give myself. Leave him work it out. It's tough because we want to know, but it is them that has to figure it out.
GAL and focus on yourself like you have been. Whatever he is doing isn't going to make you any more certain of the future. I think you are on the right path - ignoring the bad behavior and acknowledging the good.
