Our sitch really has so much similarities...I had the same feeling about what happened to my H and x-OW - that it was too soon, to early for them to have cut off contact in November. I remember posting that I should have been really happy but for some reason knew that it was not the best thing that could happen. Just like your H, contact between x-OW and my H resumed, although it is more of "stringing along" as well, with talk more about work, projects, etc. according to h (I do believe him, for some reason).
H and I talked last Sunday, and one of the things he said was that illogical as it may seem, he knows that nothing would really come out of his relationship with OW, and yet he still wants to find out for himself.
I guess the closure he needs is not there.
On another note: the convention in OW's town is coming up next week. I am so nervous.
