Dear Annie: Should I tell my best friend that her boyfriend is cheating on her?

Dear Annie: My best friend is dating a nice guy, “George” (not his real name), and they seem madly in love and want to get married after graduation. We are all college students and George is an international student from South America.

One night we went out with some friends from class at a bar/restaurant. When my best friend and I got up to go to the ladies room, some friends came over to the table, and I overheard George telling them about a date he was on the night before with another girl he met online!

I am so angry at his betrayal. Do I tell my best friend? Or is it none of my business? — Keeping Secrets

Dear Keeping: You should absolutely tell your best friend what you overheard her boyfriend saying. The fact they’ve already discussed getting married (and soon) and that he’s dating other women clearly shows they are on two very different pages. Save her the agony and headache now, before she wastes any more of her time with him, thinking he’s a good guy when he’s not.
