Just to clarify, I wasn't accusing you of that. Just asking, and if you were to be P.Oed about the "me time" it is completely understandable.
If that was the case than I can relate, I used to get so ticked off and look for anything under the sun to try to lay a boundary on. LOL! You don't want to do that.
Now.... I do think you have every right to have this shared with you. You are their mother. You just have to try to come up with a good way to place this boundary and I am confident you will.
The crazy behavior will test you like no other. You must try your very best to keep your focus on you and the kids. It's very easy to get caught up in trying to figure it all out....Dont. You can't anyway, coming up with rational answers for the irrational is impossible.
Don't be rattled by all this, it's par for the course. Focus on you and the changes you need to make, take care of yourself and your little ones.
