sucky guy

me and my ex boyfriend went out for 3 months. and then 2 months later after we broke up i found out he went out with one of my best friends not long after. something else was that everyone knew about it but me. my friend said the reason she didn't tell me was because she didn't want to hurt my feelings.

this guy starts to flirt with all my closest friends that i hang with as if i'm not there.

it is really annoying.
