I introduced my wife to biking, well reintroduced, to include her in my passion. She loves to push herself and has improved alot, but she still hasn't gotten "up to speed" (pardon the pun) to ride with my regular hammerfest and solo rides. This causes a bit of an exclusion dilema for her. I tend, but really try hard not to, feel resentful that I have to consider her schedule when wanting to ride. But that is just part of life. So yes, there has been trouble of sorts due to biking between my spouse and myself.
