Is OTHER wrong in the post ? POST : First I want to start with that I am extremly grateful that my in laws watch my kids while my husband and I work. They don't ask us to pay them or anything, but lately I feel like my mother in law is crossing some lines.

For clarification, my husband has two kids from a previous marriage that live about 45 minites away from us. My in laws will sometimes take the kids to visit their brother and sister. I am all for it, but today I lost my shit. 

So, today my mother in law texts me around 3 PM letting me know that they are going to visit and they will bring the kids home after. Apparently they are having a BBQ with my step kids. At this point I am a little peeved. She literally gave me no notice, which would be fine except my husbands ex wife wont let my kids in the house. I don't know why either. Anyway, without notice I was not able to pack my kids warm clothes and their heavy coats. They had their sweaters and thats it. Where I live it gets to be about 40 degrees but windy. I freeze if I stand outside for too long. My kids are 3 and 1!!! 

Here I am and its almost 8 PM, still waiting for my kids to come home. I called and texted my mother in law with no answer as to where they are. My kids have a bedtime of 8 and they get their baths every night. Am I the Asshole for being pissed about all of this. I know when I confront my mother in law she is going to throw it in my face about babysitting without pay, and taking the kids when they are in their care.
