My husband HATES my brother..

Ariel

Okay so when i met my husband we lived in different towns. When he would come to visit me every weekend(we only lived 2 hours away) my brother would never talk to him and he always ignored my husband. On New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> we had a party and my mom bought drinks for us, my brother just straight up slapped me in front of my husband. And recently i went to a family birthday thingy and we weren't sure if i was pregnant or not but my brother punched my stomach really hard, i got so mad. I told my husband about it and he said that next time he's going to do something about it. I didn't want him doing anything because that's my brother ya know? my brother has always hit me and stuff but my family doesnt do shit about it. On October 28th there is another family bar b que and idk what to do😳 i need some advice
