choosing a sibling over your wife

Caroline
Ok this is a proper rant so apologies in advance
To cut a long story short, myself and husband had a brief separation after the birth of our daughter in 2014. During that time his family, particularly his brother and sister in law lived only a few miles away and never came near my daughter or I, or even acknowledged our separation
Anyway my hubby and I patched things up and now his brother is still coming in the middle of us. He has deliberately ignored my birthday but not my husband's or daughter's the last 2 years. We moved house and he never offered to help, only days after we moved in his bro appeared at the door wanting a good nosey. Xmas I never got a thing off them and my husband was raging about it all saying he was done.
He has never followed through on this and now that he says everything is cushy with his brother it's like all the feelings I had before are sidelined and no consideration given. This caused a huge issue in our relationship prior to our separation and I don't want it happening again.
I feel like my hubby is a big pussy who won't stand up to his brother but he makes me feel second best whenever I mention it. I just want some advice/ opinions if ppl can help, particularly anyone who has been through similar as I'm struggling and feeling really hurt and my hubby refuses to acknowledge it when I bring it up xxx
