Should I attend this funeral?

My aunt (uncle’s wife) recently passed away unexpectedly. She was always nice to us but then I don't know what happened suddenly. People said it was jealousy but I don't know. For over a decade she treated my mom and I extremely unfairly and deeply hurt our feelings. Due to that we distanced ourselves from her to protect our mental health. A few months ago though, my aunt seemed to have wanted to reconcile, I suspect this since she actually told my Dad she wanted to chat with us and personally invite us to her home. But we couldn’t chat at the moment. We are torn if to attend the funeral or not. We would like to pay our respects and be there to support the rest of the family, but we fear her side of the family insults us. (She told many lies about us to her family). I went to the wake and no one treated my badly. A few people even asked for my mom. So I’m not sure if this means she’s welcome to the home. I’ve never experienced anything like this and believe it or not , she’s the only person we’ve ever had a riff like this with. Since she’s elder to us we never actually stood up for ourselves, we just quietly keep a distance. What should we do?
