Yes I did. I was convinced he was having an affair with our (female) personal trainer. she used to come to teh gym in our development to train both of us, but I was so ill I had to stop. I used to smell his gym kit when he got in to make sure he'd used it. At one point I actually accused him of it, citing as evidence the fact that he was showering at the gym rather than at home. I refused to believe his reason - that he didn't want to use our shower (en-suite)in case I was asleep.
