Hi Westo - I read your thread and, yes, ours is a similar story and time frame.
My H gained weight initially too but now he has lost it again and then some...I have no idea if it's on purpose or not. He does always look very tired. It did in the beginning make me think there couldn't possibly be an affair going on because he was chubby and he didn't shave or have his hair cut but, silly me, of course there was! He has also started wearing weird hippy bracelets and this an M&S clothes kind of guy... Hugs
