Who's right in this sinireo?

Guy is head over heels for a girl they go on two or three dates then she decides she just wants to be freinds. They stay freinds for awhile still talking everyday until she meets somebody and then slowly they stop talking. Things don't work out with new guy so she starts talking to first one saying she would like to try it again that she has feelings for him. Guy says no you choose someone over me ( even though still into her ) now she's mad saying he's like every other guy. Who's right should they have tried again?
