my family is realy mean to my gf?

[Joe M]

my family is realy mean to my gf. my parents complain about her all the time. my sister thinks she's not good enough for me, and 2 of my brother's say she's not worth my time. my gf dose everything she can to get my family to like her, but nothing works. my dad complain's about my gf because he thinks she needs to be more responsible, and my mom complin's about her because she dose not speak spanish. i think my gf is very responsible, and the reason she cant speak spanish is because she is orignally from japan. my mom cant speak very good English, and my gf cant speak spanish at all. what can i do so my gf is not hated by my family?
it is not a racial problem.
