I just speed read through your previous threads, and boy, have you had a wierd time! Going on your 'honeymoon' with your H's decision that he will D you right afterwards????? It would all seem funny, if it weren't so ghastly and stressful.
I can identify with so many of those strange behaviours, only when I experienced them pre bomb, I was totally naive and unsuspecting. My H could sure make a nasty situation out of thin air too. I used to ask him why he behaved like a bear with a sore head, or had he got out of the wrong side of the bed that morning? (In my ignorance I chipped in with my reactionary bad behaviour as well, you can imagine some of the scenes we had!) He too has gone from a self avowed cigarette smoke hater to a cigar and pipe smoking chimney! He also talked about how there were going to be changes, oh yes!! Even my clothes sense was bad - when I told someone that, she laughed like a drain, as H's clothes sense is hardly noted. And even OW dresses like a hippy, none of our friends are exactly from the smart set... Anyway, I know you didn't ask for just more of this "My H is/was the same" kind of stuff.
I can't advise on your situation as my H left home. While you and H are living in the same house with this going on must be very difficult, but gives you ample opportunity to DB. On the other hand, I stumbled across DBing about seven months after he left, and have only been DBing the last few weeks - under two months.
One thing EVERYONE advises, especially to newcomers, is to have vast stores of patience. I am sure you will get people stopping by before long to give you advice. Good Luck.
