What does it to be put in a bottle by a guy?

I'm really on and off with this guy. He's. Acheat and a liar but he's also my first love I truly hate it. It's been going on for like 3 years now. My guy friends are always saying he put me in a bottle. I'm not really sure what this means. Right now we are off but it's insane that I can go from absolutely hating him one day to absolutely missing him and having no idea why we are even fighting in the first place. Like one day I'll be certain I'm never going back and the other day I'm giggling and blushing at the idea of us reuniting soon. Is it normal or are we really toxic
