The solution to this cycle: DON’T GET SO ATTACHED! In my opinion, high schoolers are getting attached to their boyfriends and girlfriends way too soon and too intensley. I think it’s great that teenagers date and get to experience love or something close to it - but putting yourself out there and attaching yourself to someone makes you vulnerable and easily hurt. I don’t think love comes that easily - especially with self-obsessed teenagers. I don’t even think people are aware they are in love sometimes. Love requires a lot more introspection than we assume. Take things slowly and put yourself first rather than latching on to someone prematurely.
And smile!
