It seems to me that you have problems in your relationship that are not related to bicycling itself.

Lots of people have hobbies, and it's not too often that their partners/girlfriends/etc share their hobbies. A lot of times, that's a good thing, as it keeps them from getting on each other's nerves.

A long time ago, one of my friends made the observation that "It's the least interested person in a relationship that controls the relationship." Sounds like sort of the case here. So what happens if you don't go to the wedding, etc.?

Don't expect to find someone that likes to cycle the same places the same time at the same speed as you. That's not what makes good relationships. Even if you find that person, as the years go by, yours and her interest may change, and leave you without that common ground.
