Love / i Have been dating a polish guy for 2 years and i NEED help [10]

Hello,
I hope i can find help here from someone.
my boyfriends parents are both from poland and at times can be extremly tradtional
I met my boyfriend over two years ago adn we were friends at first i even was unable to go home for thanksgiving before we were dating and his family offered to me to go there..i thought everything was okay

A month later we started dating seriously but with his mother it went down hill
For some reason she hates me...you may think that i might be blowing out of the water but i'm not
At his sisters wedding family members came up to me and said " we don't know why she doesnt like you she just doesnt"

I have tried everything i have baked her things brought her wine when i go and visit her house ect..for a while i was not allowed to park my car in the drive way!!!

My parents even went to Poland to pick up some dogs there and i thought that would be a conversation peice but oh hell no..she bearly says anything to me

Its been two years now and i dont live in the same twon anymore and when i come up to visit i'm not allowed to stay very long

i'm extremly polite and more of a kiss ass really When and if she wants to talk to me
I'm no longer allowed at the house for holidays even though his cousins can bring there boy/girl friends
I'm just lost
I dont know if i should be baking somehting specific for her or should i make a dress and go to her house and a lil dance? any thing will help me

thanxs
