A FWB I had was being gradually more distant. I called her out on it, basically a 'hey why are you drifting away?'

She told me that it seemed like I only wanted her as a booty call, that I didn't care about her life.

It was make-or-break here, so I went with my gut, by being genuine and showing my vulnerabilities. I told her that I was distant because I was afraid of being too clingy, that I was still trying to find the balance between too clingy and too distant. I told her about how it was considered 'cool' for guys to be distant and uncaring.

It worked, and I'm meeting up again with her soon.
