getting back together with someone i've not seen in 8 years?

this guy that i dated in high school recently got a hold of me saying that he moved back here a few months ago. we’ve been talking pretty much daily for the past few weeks. i have been single for over a year, and this was def. random. i think there may be something there, but i am afraid it’s too good to be true. i feel like i’m in a book! has this happened to anyone else out there?
