My husband and I started riding together and we enjoy it. Although, I don't ride with him all the time and actually prefer some alone time on the bike. His pace is faster than mine. When we do ride together it is an easy ride for him and I use the ride to push harder than I would otherwise, so it works out.
We enjoy riding and it gives us something to do. We are planning our 10th anniversary in October as a riding trip to Hawaii. So, our riding makes the relationship easier.
If I can't go fast, at least I look good.
