Should I invite my estranged sister to my wedding?

Anonymous
So my sister and I have not seen each other since 2014. Since then, we’ve sent a few texts, happy birthday and the like, which I’ve continued, but she hasn’t reciprocated since early 2019. My mum is undiagnosed NPD or at least NPD traits and she decided at the behest of a counsellor to cut off our side of the family. She’s even had another kid in the last five years she didn’t tell any of us about.

I’m getting married next year, and I would like her and her family at the wedding. But it’s been so long that I don’t know if I should invite her, and even if I did I’m not sure she would even come! Which would break my heart all the more, given I was her maid of honour at her wedding in 2009.

Would appreciate any advice!

Sorry to clarify *my sister decided to cut us off, if that came across unclear.
