I think we broke up, what do you think ?

Yeah, if she's putting no effort into the relationship then she's not interested anymore. You should just stop texting her. Sometimes girls want things they can't have, and people never know what they've got till it's gone. If she wants to go on a break, then go for it. Or actually, just break up overall. She's trying to be indirect with breaking up with you, just tell her that it's over. Good luck!
