What should I do If I hate my husbands family?

Whats wrong with me?I love my husband but I hate him when he goes to his family...I know he is giving money to his family but he never discuss these things to me and that really irks me...he has other siblings who can share financial istance to his parents but he is always the one who shoulder all the expenses of his family even his brother who has psychiatric problem...I really hate him...i know I should be compionate to them and be kind to them because it is his family and blah blah blah but really I am not hypocrite...I hate to talk over this to my husband bec. I know this will be a BIG issue but i reaaly hate them
