Hi, girlfriend!
Good to "see" you again!
Sorry H still has unresolved issues about the OW
BUT - we all know it can take a really long time for things to die down.
Is there something you could ask him to do that would make you feel better? For me, it was my H sending OW a letter saying he didn't want her to contact him ever again. Mind you, he still dawdled over it even after he agreed to it - but once he finally did it, I felt much better.
I see it as a manifestation of the "one toe out the door" syndrome - just keeping the door to the marriage open a crack in case something better comes along. For my H, this was really important for him to understand - that this was tied up with a bigger issue of "longing" in his life - and with his fear of abandonment (therefore hedging his bets in case I dumped him).
