My MIL Sucks!!

[The edge]

This past Saturday, my niece had a birthday party plus this was the weekend that my 2 SK's were supposed to come over. We could've killed two birds with one stone IFFFFF my MIL had'nt intercepted them before we got them. Why the hell would she ask their mother's without consulting us? It's interfering bull like this that throws our visitation off. They told us tha they couldn't come because they were attending a party. IT WAS HIS NIECE'S PARTY!!! His son's mom brought him and my MIL asked her TO STAY FOR A WHILE!!! WTF! I got wind of this quick and our 3 children did not attend. We later found out that this BM was talking bad about us in front of everyone, including the kids!!! No tact, B*TCH! We actually didn't know if his daughter was coming . She came late and DIDN'T HAVE A RIDE HOME BECAUSE HER MOM ASSUMED THAT WE WOULD BE THERE!!! What kind of mother leaves a child without making sure that they have a way home, after talking to an adult. My MIL had the nerve to get mad at us when it was her fault that we did not attend. How should I/we/he approach her. We asked her several times to stay out of our business and she continues to prove that she doesn't know her place. How is it that they don't understand that if we don't get along with them, they shouldn't be around. If we can't see them easily then neither should anyone else. WTF!!!?

Your hubby needs to handle this since it is his mom and his children. He should take her out for a long talk or ask her to set aside time at her house for a talk. He needs to be brutally honest with her about his feelings and how it makes him feel when she interferes in his life. If you ask her to stay in her lane, she will only get defensive and will intrude more to piss you off.
