Is AUTHOR wrong in the post ? POST : So I  am not even sure where to begin with this shitstorm. But I am bringing this up because my mom and dad usually have my niece over during spring and summer breaks making them awkwardly always have to tell me to not come over and visit. I have also actively not attended Christmas for the past 5 years. This has caused my grandma a lot of distress because it's the one time of year my whole family gathers together. 

Getting down to the issue, 5 or so years back I was still living at my parents home (at 23) and my boyfriend(24) ended up moving in with me for a couple years so we could save up to get our own place. Winter break rolls around and my niece 11 at the time is spending a week with us. Normal week nothing weird. I was pretty much in charge of taking care of her. The thing that was bothering me though was she had gotten a kindle for Christmas and was going into chat sites. She showed me some chats she was having with guys admitting they were 20 or older and she was telling them she was 13. I got concerned and let my mom know so we changed the wifi password and pretended the internet was down the rest of her stay.

Fast forward almost a year later to October my mom shows up at my work in the middle of my shift and tells my boss there is a family emergency and I need to leave work. She drives me to a coffee shop and basically says that my niece accused my boyfriend of molesting her to a counselor at her school. This caused him to be kicked out of the house with no warning,  I went with him we slept in our car for a week then at my grandma's for another luckily we found an apartment after that. I'm glossing over a lot of hardship and drama so we can get to the point. 

So a few years pass things are awkward I pretty much convinced my whole family minus my sister and her husband aka my niece's parents that my boyfriend was innocent and finally she even confessed to my mom just this past winter break that nothing happened now that she is 16 and a bit more mature. Basically she broke down crying and felt awful and just wanted to see us again. I'd also just got married to said boyfriend so I think this sparked the conversation. 

My mom is fully expecting me to have a chat with her and try to work things out so I can rejoin Christmas. I just feel like she ruined a huge part of my life. I'm still getting anxiety stress just typing this out. I  get that she was just a dumb kid with overactive fantasies.  Am I maybe angry at the wrong person? 

Tldr; neice accused my boyfriend(now husband)of molesting her, years later confessed it wasn't true. Mom wants me to reconcile with her so I can attend Christmas.
