Biking helps in so many ways! When my s.o. and I are too grumpy to speak, we go for a bike ride. Or multiple multiple RIDES. When I moved out for a while we still met for rides. When you do something you love together, it's easier to remember that you really do love that person. (even if they aren't perfect. 'Course, we are perfect, it's just them that aren't perfect...)
I agree with the others, you'll find someone when you least expect it.
(seems like the ones I find when I'm LOOKING are the worst)
