AITA for not inviting my bestfriend to my wedding ?
I'm a 33 year old M and is about to get married in a few weeks. My bestfriend is a 33 year old F (B). Some background information B and I have been best friends since we were in high school to college. Back in high school I didn't have much friends or have a group of friends that I belonged to. Then I met B. B introduced me to her friends and brought me along to school clubs which in turn gave me the confidence to be more social. She accepted me for who I am when I came out. When we attended college we became roommates and gotten closer to the point that I consider her a sister. Then I met my fiance while in college. I admit that since meeting my fiance I became distant and spent most of my time with my fiance. I didn't have much time for my friendship with B. We graduated college. B and I went our separate ways. B relocated to a different city hours away and went back to school for her masters. I moved back to our home town and went back to school to pursue another degree/career. Our communication lessened with occasional text messages and hang outs when B is in town. Time passed by my career took off and I moved in with my fiance. We are adulting. As time passed by things have changed. B has changed. Her messages became erratic. She became paranoid. B would tell me that her coworkers would mess with her stuff by putting chemicals in her water bottle and moving her arm chair in a different directions. How her parents are spying on her by having a camera and listening device in her room. How her dad would pull the clothing strand of her shirt to ruin her clothing. How her dad has conspired with gang members to intimidate her. Relatives conspiring to hurt her. Her own sister sabotaging her and putting her in dangerous situations. How a friend in high school has stolen her reproductive eggs. How she was drugged so that her reproductive eggs can be stolen. Her personality changed. Signs and symptoms of schizophrenia. I attempted to help by suggesting seeking professional help however she refuses. I reached out to her family but she isolated herself. Things then spiraled and she turned against me. B started accusing me of conspiring with old high school friends ( I haven't spoke to in years) of stealing her identity. Started accusing me of being a bad friend by using her setting her up to fail in her relationships. Her messages to me became unsettling. Threatening like. Erratic. I last responded to her messages June of 2025. I stopped responding because I feel hurt. She continuous to message me but I don't respond because I feel hurt. She has not apologize for the things she has accused me of. She's not once asked me how I'm doing. Her messages are just... Nonsense and full of paranoia. I decided to just cut her off.
I wanted her to be my maid of honor because she was my best friend. A sister. To be part of my life. Now, she's not even invited to my wedding. I feel guilty thinking/feeling that I should do more to help her. AITA?
