Everything you listed as not having in common were hobbies or activities. My husband and I don't really have these things in common either, but we have personality-type things in common. If you can make each other laugh or have lengthy conversations about nothing, these are things you have 'in common.' It's not just about what activities you do. Those things may change over time, but your personalities won't (that much). I have a lot in common 'activity-wise' with a bunch of dudes at the DZ, but I sure as hell don't want to spend the rest of my life with them. Just something to think about.
