What should I do?

I feel when anyone is mean to my husband or talks shit about them I attack them like a lioness, even if they are my family. But my husband on the other hand might realize if his family was mean to me but do nothing about it then, come to me later to wipe my tears. Is that right? It makes me feel that I cannot expect him to ever fight for me or to stand with me against others. These situations have been cropping up since last year when we decided it was time to hitched.
