I agree with Mimi. I think my marriage and my hubby's feelings would have to come first, even if I knew there was no real concern. We can't help the way we feel and I am pretty sure that if my husband rode regularly with another woman was much more his equal in cycling, I'd be jealous even if it waas't a trust issue. I think the more you ride with your hubby, the stronger he will become so it will no longer be an issue. Maybe you could do club rides with a larger group when you feel the need to hammer?
