Ya I had a girlfriend like that and if she texts you messages that long by the first few dates get out fast. Get out before it's too late because then you'll have huge regrets about your like. Please read this and just tell her that you don't want to date her. ( if you really don't want to). But just break up with her no matter the cost even if you look like a total asshole just do it. You'll regret not doing it later. You won't have any room to do anything if you do date her. Just know that now. Good luck.
