What can I do with my marriage?

My husband (29m) and I (29f) have been married for almost 6 months. For context, my husband's family called me a gold digger and my BIL said I married my husband for the money although my parents literally bought a house for my husband and I to live in. The issue is my husband doesn't stand up for me, he smilesld and cheered his brother on to talk to me like. I felt humiliated and defeated.

Its been a month and I haven't spoken to his family since but my husband has still been staying over at their place for 3-4 days every 2 weeks. Sometimes he goes there during weekends and since he works long hours I don't spend any quality time with him.

It's now gotten to the point where he spends a week there, and only a week with me. He said I have to "deal with it" if I can't get along with his family, but that's not going to stop him from spending 50% of the time there.

I'm literally sick of giving myself false hope and I'm not sure what to do.
