Honestly don't be that girl.
That girl who goes back continuously thinking every time will be different. I understand you miss him, and it's easier to breathe with him around. But isn't it easier to smile when he's not breaking up with you or getting mad at you for no reason? You don't deserve to be the back up. The person he drops and picks up whenever he feels like it. Don't be that girl. That girl who thinks each time he comes around he means what he says, and won't leave again, everyone knows he will, and you end up looking like a fool in the end.. again. I get that you're happier when he's texting you and cuddling you. But aren't you happier when you're not on the floor crying because you haven't heard a word from him all day? No one can tell you who to be. But don't be that girl. You're smarter than that girl, stronger than that girl. And you're worth a lot more than that girl.
