I love my fiancé but his family doesn’t CAUSE IM BLACK!?

Quick rant😩 sorry it’s a tad but long but I need advice.

Me and my soon to be husband to be are getting married in February. We just found out we are pregnant and due in July. We just had a big fight with his brother and mother last Monday. It was because his brother thought it was okay to pick on me because I’m currently not working and tell racist jokes and he can get away with it. My fiancé makes well over enough for the both of us and he told me to quit my job. I told my fiancé he hurt my feelings and he called and told his brother CALMLY that what he said was hurtful. He cusses him out and calls him names for sticking up for me.His mom came over and blew her lid on me and she didn’t know our side of the story yet. She said hurtful things to me. By the end of the fight she apologized and tried to hug me but I wasn’t having it. I never called her a NASTY word or put my hands on her. But she defended his brother because he has ANGER ISSUES. He told me he would understand if I left him cause of how they treated me.

THANKSGIVING COMES AND GOES AND WE SPENT TIME WITH HIS SISTER AND MY FAMILY.

We are pregnant. This is his first kid and he is the baby of the family. He wants to tell them eventually but I’m not wanting to tell them. What should I do? Upvote so we don’t get lost
