<human>: My ex gf broke up with me about 4 months ago thinking that it would be better for the both of us. She's tried talking to me a few times since and I've blown her off because I was still slightly angry. She wants to get back together and I'm torn. She's been popping into my head more and more recently and I'm not sure why. I don't really want anything too serious as I'll be going to college soon and I kind of want to talk to her but have no idea where to begin. 
I could really use any advice you could give.

Can you summarize the given text in a few sentences?
