Firstly, I do like your SZ defence - made me laugh.
I am saying why has the OP twice texted SZ to say she is happy to put it behind her when she clearly doesn't mean it?
Secondly though, OP has clearly stated she DOES want to put it behind her. She just wants to move on and forget it happened. Afterall she is going through enough as it is.
Why doesn't she just answer the phone to someone who says they want to sort it out calmly and find out what the woman has to say?
Calm isn't in SZ's vocabulary. She's clearly demonstrated this through her threats and lies. I don't know anyone in their right mind who would want to take that call to potentially be manipulated more. She's toxic and wants the indulgence of the OP's solo attention away from other witnesses to try and manipulate the situation to her own deluded advantage. Ignorance really is the best route - only people who haven't grown up enough to be able to just let things go and mark it down to experience would find the ignorance a problem. SZ just isn't getting the message. We don't have to speak to people if we don't want to, and we shouldn't have to. If a friendship has been ruined it's time to move on.
And mostly, gathering a posse to "turn up together" and cause awkwardness and potentially a scene at a child's birthday party is akin to playground behaviour from all the grown women on both sides of this unnecessary feud the OP has allowed to develop.
The OP hasn't allowed this to develop. She offered the olive branch early on to let things lie and move on. SZ wasn't satisfied with this response - she WANTS the drama. It sounds like she's got it in for the OP from the sounds of all the watching things happen regarding finances. And it's not a posse. They aren't strutting in to the party to Destiny's Child's Independent Women on full blast - OP is simply taking the cake with party friend and other friend. Besides which they're going early and so SZ won't even witness them arriving together.
