<human>: Can you succinctly summarize the text in 1-3 sentences?

I (F/21) am having a hard time figuring this out. 

We dated from May-December 2010

I was almost 18 and he was 21. Long story short, he wanted a fuck buddy, I wanted an exclusive relationship. 

It was my first relationship so I was naive and slowly learning things.

 We broke up and moved on. Hes (M/24)not single. I'm not single. 

He checks up on me every few months and this time he asked if Id be interested in hanging out. 

I cant figure out if he really wants to be friends or has other intentions. Big part of me is saying the latter. 

What is up
<bot>: ex wants to hang out. Confused as to what to do because ive heard of people being friends with exes
