Hmm, i had just about the exact same conversation with my wife a month or so ago when I went from riding a couple times a week to really ramping up some mileage because I was enjoying riding so much. Basically our solution was I only go out once a week where it takes time away from the family and that's a Mondy night ride. The rest of my ride time is taken out of my own personal time which means I get my butt up way early on the weekends and ride both mornings. Then we also take out the tandem on Tuesdays for some us time.

In our case, it was an issue of her thinking I was shirking my responsibilities by going off biking and/or not spending enough time with the family. We just compromised how we could both make it work and so far it's been good. Now she is a stay at home mom so it's a bit different with us in the fact that part of her resentment comes from the fact that she see's me getting out of the house and wishes for some time for herself so we also worked it to where she can get out one night a week on her own too if she chooses and I'll watch the baby.
