Does anyone have any advice on how to deal with jealous Mother in law?  

Yup, the only child!! I wish I lived out of state, I'm only 10 minutes from the lunatic!!

I had an ex-fiance who's mom was jealous towards me. So was his older sister. Your man doesn't have to be an "only child" in order to have a jealous mother - mine had six siblings, ages ranging from 3 yrs.old all the way up to 26 years old (back then - this was about 8 yrs ago)!

I was younger, thinner, prettier (the mom & sister were as ugly as sin - inside and outside - and never happy with their weight), and I wasn't bogged down with a bunch of children, and I was obviously a lot smarter than the both of them combined. (They both dropped out of highschool, and thought that people who went to college were a$$holes with too much money, and they both made a lot of serious mistakes in life.) I'm not saying that because they made these mistakes that they're worthless - I'm just saying don't look down on me because I have a good head on my shoulders, and know what I want out of life, and am not going to let someone or something drag me down and keep me from achieving my goals... Anyway, mind you, I never acted stuck-up or conceited; I am not one to act conceited (until you start acting like an A$$ towards me for no good reason - then you deserve it!) I never gave them a reason to be hateful towards me; they just decided they didn't like me, and when I sat and thought about it, I figured out why - it was jealousy.

He never stuck up for me, either. The one time he did, him & his whole family ended up in a brawl. His mom was acting really hateful towards me for no reason (yet again), and he had had enough of her attitude (and so had I.) I vowed never to step foot inside her house again because I know not to tread where I'm unwanted. I kept to that vow until I broke off the engagement with him, two years later.

If I were you, since you *ARE* married, I would move to another state to "start over." If I would have done this with him, I would have just been in a different state with an emotionally/verbally abusive man - it wouldn't have made any difference. But since your man doesn't seem to be abusive, I suggest moving. And put it to him gently, but firmly: "Hon, perhaps it would be in our best interest to move to another state to start our lives out fresh. Your mother is really putting a big strain on our relationship, and I can't take it anymore." If he balks or makes excuses, just be firmer: "Are you listening to me? Our relationship is in jeopardy! This is serious!" If he doesn't want to listen, be prepared to move yourself to a hotel room for a few days to show him you're serious and that you're not taking any more of her CRAP! If you don't stand up for yourself (and your relationship), then who will?
