Boss being weird over me asking off for wedding/events?

Hello everyone. I (27f) have been working at my very small institution for about 5 years now. I am getting married soon and will need several weekends off for that. For reference I work one day out of the weekend and my boss works the other. When I cant work my weekend day I try to make it up by working a full weekend either the weekend before or after that weekend. The last weekend I needed off was in June, due to a family medical emergency, and other than that I haven’t needed a full weekend off since probably 2024. My boss generally is weird if I need a day off and complains to others that I am just “never at work” which is absurd because I am there for the 20 hours I am scheduled every week and even if I work above that I don’t get paid extra (still hourly btw not salaried) Well 6 months ago, she asked me to outline how much time I will need off for my wedding,which I told her, and she freaked out. I need 4 weekends off in the next 2 months. I understand that sucks but I told her about this 9 months before the wedding. Now she’s refusing to give me my full time off for things like my Bach weekend and honeymoon and making snide and offensive comments to me about them. I am generally a passive person but I can’t be passive about this. I can’t really afford to quit but I am just so frustrated with the childish behavior (bc yes this goes even deeper than this, she loves to name call and scream and throw things around her office). I just don’t know what to do lol.
