<human>: My ex is and was my first love, plain and simple. I'm sure the story of how we met is in some kind of cheesy romance movie but yeah. She left me to go pursue the "college life". Every now and then she comes around and really turns my life upside down. There has been back and forth hints and whispers about getting back together and this time I know shes going to be coming back around. But to get to the current issue, There is another girl that I'm talking to kind of, shes really cute and makes me happy but I don't want the past to come back and bite me on the ass, or I don't want my past to come back and have me hurt the new girl. I'd love some advice and or help

Can you condense the text into a few key points?
<bot>: The one that got away likes to visit out of the blue and mess with my head and heart. Shes my first love, and there is a new girl that makes me happy.
