I've been going on the back of my partners bike for 12 years now. I haven't really enjoyed it but done it because it's his passion. We've been to lots of places on it including Spain & France. I told him today that I no longer want to go on it. I find that my back aches and my hip hurts. I'm 53 now and feel I've had enough. He has now given me the silent treatment and made me feel bad for not wanting to do it any more. He said what's the point of us being together if we have nothing in common. AIBU??
