To cut a long story short, me and my friend have been friends for around 10 years. We both have 2 children who are all the same ages and in the same years at school. Her child recently wound my son up at school and he reacted and threatened her with telling me and said I would sort her out. Not saying threats is the right behaviour but her child came out that same day before my son and told me he had threatened her for no reason. Turned out, as I said that it wasn't for no reason and she had been mean all day with her friends to him. I was upset that she would lie to me when she knew me but I know she's just a child. I said I would speak to my friend about the situation. The next day I didn't take the children to school so my husband bumped into my friend instead and he had words. Her daughter cried over being caught out and when my husband left, my friend reported my husband to the school without mentioning it to me before, during or after. I found out when school called about my husband apparently making a child cry on site. He said he only had a quiet word. Am I wrong to be upset that she didn't talk to me first after such a close friendship if she didn't agree with what he said? She tried to carry on as if she hadn't done it. I ignored her and she chose to keep her distance since which proves how much I'm worth to her right? That's the end of the friendship. We've had some very off/on/strange things happen in these 10 years but mainly been very close.
