Am I wrong?

My parents have a toxic relationship. My dad is definitely the crazier one but I don’t think my mom is as innocent as she tries to play it off. I kind of feel like part of why she stays is for attention. She’s label all the things he does - like when he lovebombs her, for example, she always calls it. And ALL she EVER talks about is my dad - over. and over. and over. Sometimes it’s even the same conversations over and over. And sometimes it’s the same conversations about how “she’s in trouble”, “save her” jokes, etc. It just seems like she’s just looking for attention sometimes. I work weird hours and am a single mom so I’m already tired. So with all of the different things involved, I get tired of hearing about it really quickly. I just don’t have the patience to always hear “your dad did this and I know it means this” or “your dad said this but I know it’s just this”. I want to be there for her because I was in two abusive relationships back to back. But it just gets really old. Especially since it’s been like this for 5 years and they/she only get worse. But my brother says I’m “being mean” if I get annoyed while talking to her
