You do just fine at your English, please don't feel it necessary to apologize.
I hate to be the one to bring this up, but I see some things in your descriptions of your H that make the lightbulbs go on, You stated at the beginning of your thread that there was not an OW, but are you positive?
In the days and months before my husbands A was revealed he too displayed a marked disinterest in sex. He had unaccounted for time and resented accounting for his whereabouts.
Does anyone else besides me think this might be a possibility?
Andrea could you take any steps to find out about this w/o coming and asking H directly?
Sorry to be a messenger of doom, but I just see so many similiarities.
