Yea, a friend of mine was cheated on, and my advice was to move on. Of course, easier said than done. :/
Sometimes advice is not the thing that someone needs most (says me as I give you advice) Expressing the sentiments in your haiku to your friend might be more valuable. Just so your friend knows you wish you could take the pain away. Maybe spend some time with them.
True. You are a wise one, newbie one. That tends to be my advice in general when feeling wronged-just delete the person from your life. I know that it isn’t always that easy.
