My husband convinced me to betray my only sibling

Throwaway account for obvious reasons.<br><br>I only have one sibling, a younger brother. My father died when I was 7, and my mother died when I was 19. <br><br>I'm 24 now. My brother is 21. He got admitted into a college in another state about a year and a half ago. I regularly texted and called him when he was there. I never cared about the details of what he's doing or who he's drinking with. I just wanted to see if he was okay.<br><br>I met my husband when I was 19. I married him when I was 23. Over the few years that I got to know him, I saw the most wonderful sides of him. He's incredibly smart. He's always supporting me. He's kind. He looks after me wonderfully.<br><br>He has some flaws too, but he's always willing to change. He gets angry when I make a big mistake, but never over little things. It's completely reasonable to me.<br><br>I thought that my husband and my brother were getting along fine. My brother never said anything bad about my husband to me. My brother was cordial and polite whenever he was around. My husband also did many favors for my brother that he never had to do. <br><br>But two months ago I discovered that my brother was badmouthing my husband to relatives. My husband and I then talked, and he said that my brother was making fun of him behind his back. I was very conflicted, but I finally decided to trust my husband and talk to my brother.<br><br>My brother started acting strangely defensive, but I brushed it off and asked him to stop.<br><br>Two weeks ago my brother started yelling at me for asking him to stop. He said that my husband was controlling me and making me do what he wanted. He said I was weak for letting my husband boss me around. He said I should stop trying to parent him and focus on dealing with my husband.<br><br>I was really angry and asked him to stop. I told him he was being very hurtful. He started yelling more at me and kept saying I was blind. He said my husband was being manipulative and I was falling for it.<br><br>I didn't even get a word in edgewise.<br><br>Then my husband came in the room and I started crying. My husband hugged me and said to ask my brother to leave. My brother started yelling at him, and my husband said he was being too loud and kicked him out.<br><br>Now my brother hasn't spoken to me for two weeks. He said I'm too stupid to see that my husband is manipulating me, and he doesn't want to see me until I realise that for myself.<br><br>I don't think my husband is manipulating me, though. I think my husband is just expressing his opinions about things that affect him too. He always lets me have the final say whenever we make decisions about things that affect us both.<br><br>I just feel really bad about the whole thing. I don't know how to make my brother trust my husband again. I don't want to lose my relationship with my brother, but I also can't make myself doubt my husband.<br><br>I feel like a failure. I ruined my relationship with my brother because I didn't try harder to repair it.<br><br>I'm not really sure what to do now.
