This is what this week's letter writer had to say:

"My ex-girlfriend has been with a new guy for a year, and she got with him when we were still together.  But the past few months she's been sending me naughty text messages.  I don't want any part of it, because she dumped me, so I don't respond. Should I tell my ex's new boyfriend that she's sexting me?  Shouldn't this guy know he can't trust her?"

You want MY opinion? Don't say anything. Don't get involved. He can find out on his own. You don't owe him anything and it will just cause drama and problems in your life! It's not worth it!
