should I leave my husband??? his family is harassing me.

He and I got into a fight one day and he told his family about it and now they hate me for it . I don't care that they hate me but they keep disrespecting me. His aunt msg'd me being real disrespectful and she was commenting on my fb calling me names but I deleted it. So earlier this morning I seen a msg from her calling me bitches and hoes and that my husband is going to leave me and that she has another woman for him so I responded calling her ignorant and telling her to mind her business (which is why she responded with the msg above) her son thens comments on my page being disrespectful and my husband has said nothing about it other than I never should've responded to his aunt. I feel so humiliated and hurt. Why won't he take up for me ? I would never let my family do this to him. I understand that what I did hurt him, but do I deserve this from his family??? I have never done anything to them, HONESTLY. I never come around them bc I always felt like they didn't like me. What my husband and I go through is our business and just bc they don't like it doesn't give them the right to be disrespectful to me. I think it's more so my husbands fault for telling our business to begin with but what should I do????
