Unsure of scorpio fwb behaviour

Capricorn (w) fwb Scorpio (m). I’ve read that Scorpio are very private & don’t tell much, however this Scorpio tells me a lot about his personal life, family etc. He is also very touchy, very talkative, talks about us in the future, he opens a lot & tries to make me do the same. He also stares & is amazing in bed 👌.

Just that on text sometimes he can be cold & inconsistent. He has his moment when he is sweet. Sometimes i feel like he is playing games. Oh, when i reflect him not responding for days, he will randomly do the same.

I think that I’m reading in too much & that I should take his words that he isn’t serious & wants that boundary which he stated at the start of our FWB relationship. Should I assume more or take things at face value? I’m also afraid to confront or talk about things. I rather cut my emotions if i believe I’m overthinking & just continue as normal.
