Emily, stop! Do not call your H. It will not make you feel better, it will make you feel worse.

Only 3 things could happen:

1) He's rude to you -- you feel bad and angry
2) He's nice to you -- you feel confused and all your progress slides away
3) The OW gets your number and starts harrassing you again

Let. It. Go. Just for today. Take deep breaths.

Not calling gives YOU the power. It gives YOU the upper hand and makes him wonder. Believe me, you don't think he is, but he is. Don't lose all that progress in a moment of weakness.

Please.
