<human>: Can you provide a brief overview of the text?

My husband and I have been together just short of seven years (with  a couple breaks in between). This summer, we were married, and his mother took it really hard. She began lashing out at me, became very passive aggressive, and began blaming me for all sorts of family issues. This was all new behaviour, as she used to be very supportive of me/our relationship, and has helped us a lot over the years. 

She has been unbelievably difficult to deal with, and every interaction is tense, uncomfortable, and causes me serious stress and anxiety. It has put stress on mine and my husband's relationship, though he doesn't disagree that she is being difficult and rude. His advice is to fight back with kindness, and do my best not to let her behaviour negatively effect us- simply to continue to show love, and hope she lets it go. I am polite, helpful, and nice (even if it feels strained).

How can I help fix this? Is there anything I can do aside from what I have been? Any help is very much appreciated.... I never thought that our relationship (hers and mine) would end up being such a typical dragon-in-law/ daughter-in-law scenario, and it's caused too many tears.
<bot>: Dragon(mother)-in-law's behaviour towards me (daughter-in-law) changed drastically right before wedding to her son- HELP!!!
