Take it from a guy who has been married for a lot longer than you've been around.
Ideally you should both share a "respect" for each other's hobbies. You dont have to share the same hobbies (that's nice but not always feasible). As long as you give each other room to enjoy your hobbies that's all you can ask.
Also, balance in life is important. If ridng your bike (or whatever you do) keeps you from spending quality time together, you will have problems.
In my case, the fact that my wife and I enjoy different activities makes life's journey richer and more interesting.
You are young, use this "down time" as an opportunity for some introspection and self-development. Grow as a person and don't be in too much of a hurry to hook up again.
NOTE: I just read your update. I agree with Macka...you dodged a bullet there!
