She didn't mean that when she said she likes cycling but it doesn't like her that in other words she's not very good at it? And the fact that she is fitter now she might feel more qualified to cycle more? I don't know, that's how I read it.
This is how I took it, too. Like maybe she loves the idea of cycling and fell or something before, therefore never really learning how to ride a bike.
Not trying to downplay or invalidate your feeling state at all, mango_flower. It's just sometimes better for me to not jump to worst case scenarios.
How is this helping you to detach? If it is in a way, then carry on... .

I so wish it WAS that... . she has a respiratory problem, but used to be really into sport before she got her condition. So when she said she loved cycling but it didn't love her, it was in the context of she enjoyed it, but couldn't cycle far due to her health. Which is very different from never even having ridden a bike at all... .
I felt she was lying at the time, but had no proof and didn't think of it again afterwards.
It's helping me detach in a weird way because I am realising that so much of what we had was a lie :'(
