I Need Some Advice

[sage igloo]

My brother is going to get married on the 26th but his fiance feels shady. She is always wearing tight and see through clothes, she has bad manners, she seems very spoiled, and I think she changed my brother. He barely spends time with us as a family and will drop everything if she calls him no matter the cause even when we are traveling and even in the night. He literally skips out of church just to talk to her for a few minutes. And every time we express concern he lashes out on my mom and sister a lot and sometimes even my siblings that did nothing to him and starts bad talking about us to her. I don't know how to feel and I i'm not sure if I should still hold a relationship with him after the wedding, because i overheard him saying that he is going to drop us out of his life.
TLDR; My brother is going to marry a shady women that seems toxic, and even thought our family is showing him her red flags and are concerned he is ignoring us and lashing out on us.

Well if you’re worried, maybe see a therapist, and maybe try to get him one too. Also if she seems a bit like “bad intentions” shady, tell someone outside of your family who you know. Maybe even let your brother’s friends know too.

His friends tried to talk him out of it but he just laughs it off and thinks of it like a joke. They told me that when they are still trying to tell him that this is toxic but he just cuts them off for a while and doesn't speak to them for days.

Well then I can't think of anything else. I'm very sorry for you, I hope this gets solved instead of turning into something where he completely relies on her.
