So there is this guy with a startup, who wants me to work with him like a co-founder, putting innovations in to the startup. But I want to work like an intern, I will code, you will pay me money, if something breaks, I'm out.

Idk for how long, we can continue like this. Sometimes I feel I should leave, but then I think about the extra pocket money (I am a student). But he calls me like 10 times a day, talking for 15-30 minutes on phone, repeating the same things again and again, which really pisses me off as an introvert.

Should I leave the extra pocket money for some peace of mind?
