moh troubles!!

Hello ladies! Where to start? I’m so hurt and irritated. Since day one I asked my cousin (like a sister) to be my Maid of honor. Since I was little I always had it planned that she would be that title. Here recently she’s been in a blah mood, not excited and just a mood killer. She hasn’t helped me on ANYTHING, didn’t go to bachelorette party Bc she had to work when I found out she didn’t, not to mention told me I’ve made it exhausting. She told me that I’ve made a lot of changes and giving short notices when I haven’t changed anything. And told people about paying for their makeup and hair 6+ months in advance. I told her just to give me all my stuff (dress and boots) which I paid for as a thank you gift. She seemed like she didn’t care about it anyways. ( she’s a person if it ain’t about her she’s not interested). Now I don’t have a MOH. What are y’all’s thoughts? Did I make the right decision? I figured I didn’t need the stress and not carry her weight on my shoulders too.
