<human>: Give me the gist of the text in a nutshell

so i've been talking to this girl for a couple weeks but barley started hanging out with her a couple days ago. so i first met her sophomore of high school nothing ever happened between us. 2 years later(present time) we started talking through twitter and she wanted to hang out for her birthday weekend. Friday night/sunday morning we went for bowling and dennys, apparently her psycho ex boyfriend was following us. i had no idea.

 this morning at 4am
