Listen to me vent and perhaps give me some advice?

I wish I had a story for you, but I don't. Sorry! Here's my advice...
Now, for one, you can't expect your husband to take your side on everything. I mean, it's his mom. But it is absolutely ridiculous that he would threaten a divorce! That is NOT ok!
Two, the Facebook thing is not ok, either. Print that stuff off and keep it in a file. That could be useful.
Three, you need to keep your chin up. If you cook horribly, (which, of course, you don't!) that is none! of your mother-in-law's business. Don't let her tell you what to do. Just say, "Now, (insert her name here), I get that. I will try to give that a go in the future, but for now, this is what I'm doing."
Four, sit down with your husband and his mother and talk things out. I think she just misses her little boy.
Good luck! I hope you work things out!
