Mother-In-Law

I have been married 7yrs and lived in london all that time. We have now moved to austrlia and live in the same town as my husband`s parents. We lived with them the first 2 weeks and it was hell! trying to get over jet lag while having 2 toddlers also struggling with jet lag was awful but on top of it my mother -in-law added more stress. She is hot and cold. Telling me the one minute she wants a great relationship with me and gives me a hug and then the next minute behaving the total oppisite by being critical and harsh. After spending 3hrs trying to get my littltle boy to fall asleep i fell asleep next to him out of exhaustion. When i then came into the living room she gave me a glare that scared the living daylights out of me and said could i please tidy the bathroom of the kid`s toys. It was my husbands chore as we share tasks having two babies. My husband confronted her when I left the room but she has not appologised instead she said she can`t see anything wrong as I was sleeping and when her husband was working and she stayed home she did everything which i know is not true! I have tried to be friendly and forthcoming even though I have moved miles to a new country and has been under a lot off stress. Now i just want to keep ignoring her. When i did she said she is not invisible but i`d rather ignore her than having to face her grumpy angry face. Her anger and mood swings really puts me off. We moved the same day we found a place of our own and even though i stopped ignoring her the last couple of days before we left i don`t think i can or want to put up the hypocrisy.
