Sister in law

So me and her were cool before I got engaged. She was upset me and my husband got engaged before her and my brother because they knew each other longer. She got engaged to my brother a couple of months after, so we were planning our own weddings. Jealous hit her some how and she said I was stealing her day. Um our wedding were 2 months apart and completely different. She was saying I stole her color but she had like 7 colors and my theme was mint so yeah anyways she wouldnt talk to me about her wedding like I was gonna steal her ideas and they didn't include me in my wedding which hurt me a lot. She got drunk one night apologized and said she was jealous but nothing changed since then. I was hoping after our weddings we'd be close again but now when I see her she like stares at me like I did something wrong.
