I don’t think there is such thing as a proverbial note book. If you meant black book you still wouldn’t make sense.

He sounds like a wanker.

I'm guessing you're young since more experienced people wouldn't put up with that. If your older, wiser you could give you advice on this, they'd tell you to tell him to knock that sh*t off and appreciate you for who you are or it isn't going to work. Stand up for yourself, you'll be glad you did, it feels really good.

That's emotional abuse. Don't put up with that one moment longer. Tell him how that's affecting you and if he won't listen and stop that behaviour, leave him. However, he sounds like an immature asshole for stooping that low so you should leave him anyway.

Time to break up Probably make you nervous about doing so, and given how most people are, you probably wont break up. But you deserve better

Bite his dick and then suggest he make a note about it.

Did you mean metaphorical notebook? Or was it a literal notebook? Because I don’t think proverbial notebook is a thing in English.

That guy is an ass! I would say goodbye now and save yourself some heartache later!

Go ahead and continue having sex with him. Afterwards, pull out a notebook and speak aloud as you write: "once again...could not last long enough..was less satisfying than the last time" get dressed in active wear and when he asks if you're going to work out respond with "gotta work off the frustration somehow, maybe I'll get on a bike, at least I can ride that consistently into finishing" 💁🏽‍♀️

That’s when you take out your ruler. When he asks what your are doing, just taking down short notes for later. ;)
