Perhaps no one wants a needy, clingy girl, but HE wants YOU.
It sounds like you're under more stress than usual, if you just had 12 fights but presumably there was a time when you didn't. Is something changing?

Maybe you can't control your feelings or change them, at least not without therapy and/or medication, but you can control what you say. "You're pushing me away right now" invites him to contradict you, but takes away his agency (you decided what he was doing, not him). Something like "I'm afraid of losing you right this moment, will you reassure me that way I like?" Gets you a pretty similar response, but it looks like a request honored instead of spoiling for a fight. Both words get you what you need, but the first begs for confrontation while the second is one free person helping another.

I'm sorry this is proving hard and I know a change in language seems like a petty and surface approach to a real problem. It might help, though. That's the only fast thing I've got - therapy and patience for the slow stuff.
