Aitah for not inviting her to my wedding?

I (28F) live with my brother, Max (32m) his gf, Susan (28F) their daughter and my mom in my mom’s house. Me & Susan was cool.. until I started hearing xes noises from their room. LOUD. Ofc, I’m furious with both Susan and max because of it. I messaged max about it and basically we ended up arguing and things got heated. After this (1 year ago) I only be cordial but nothing more. Max also cheats on Susan. Now the problem is Susan is my nieces mom & my niece is in the wedding. I feel like a wedding is sacred. If we don’t speak in the same house what you need to be to my wedding for? Some saying I’m the AH & others say I’m not. I don’t want Susan there because we have no relationship. And defining something based on because she is my nieces mom is not reasonable enough for me tbh
