He has'nt been the best boyfriend, he stood me up. He broke it off indirectly, I generally felt disregarded, his birthday is next week but I don't know if I should call him

Why?
He was a rubbish boyfriend from what you say and he broke up with you in a cowardly manner.

Don't waste your time or money on phoning him.

Don't contact him. He wasn't a good boyfriend and it just didn't work out, so l just let it be.

NO! End of story

Hells to the No

Why reward a lousy boyfriend, by caring about his birthday, when he didn't care about you period?
