Dear Queenie,
I broke up with my boyfriend a while back but now I know it was a big mistake and I really want him back.
Queenie, how can I get him to give me another chance?—Sad ex-girlfriend
Dear Ex,
You can tell him you know now that you made a big mistake and beg him to try again, but if he is not willing to do so, you will have to let him go. Nothing is quite as unattractive as desperate unrequited love.
