funny everyone says on a break means it's over, when imo on a break means a very short term emotional spaz where the girl feels unloved and wants you to prove your love so "leaves" you and waits to see what you do next.
i'm shocked at how quickly the op suggested looking for the next girl as well. even if i've just had 3/4 dates with a girl and decide it's not working, i'm not instantly thinking ok next girl.
everyone seems to be ****ging the girl off but from what you've put i'd say you're the one making all the mistakes here, and you're 5 years older.
