My exAH did the same thing...I heard the "I haven't used" umpteen times over several months and he had a girlfriend. The catch to this was that (codie phase) I was monitoring his cell phone calls on the computer and he was calling his dealer (MANY times) right before he called me and immediately after. Sorry to be cynical, but I see a lot of quacking going on here. Don't fall for it.
Hugs,
Susie
