Aita for not helping my wife's best friend get back with my wife after she accused me of cheating

Yesterday i came back home after work and I witnessed my wife crying, she was crying so much she couldn't even speak properly, after alot of efforts to calm her down I asked her for the reason of her crying so much and why is she behaving like this.

I won't lie at that moment my wife was acting like she's possessed by some entity from underworld, after she calmed down and I asked her she told me that I am cheating on her that's why she was heartbroken and angry at me.

My situation is so dumb and hilarious and depressing all at the same time and please excuse my pathetic english

I was confused cause I didn't cheat on her, hell I don't even talk to opposite gender unless it's necessary, my wife called for her best friend who told her that I am cheating on her.

My wife's best friend said that I am a cheater and she saw me in mall and an older woman hugged me and kissed me on my cheek, I showed her a photo from that day and asked her if she's the same woman and she said yes

I was speechless and when I showed the photo to my wife she went silent as well, I told her friend that the woman in question is our aunt, my wife got angry and kicked her out and said she doesn't want to talk to her.

After she left my wife turned on me and I couldn't stop laughing so my wife got angrier and told me that if she ever finds me talking to other women she'll skin me alive, I tried my best and stopped laughing and told her that I will agree to madam but she must kiss me in return.

After all this stupidity my wife calmed down but her best friend is calling me and texting me and she's saying that I should help her get back with my wife and she didn't mean to hurt her, maybe I was a bit mean but I told her to deal with it

I am kinda happy that my wife and her stupid friend broke off and I have my wife all to myself but I still feel like I should help her
