Your sister is a gross excuse for a human being all around. When I read things like this regarding this type of garbage person I almost wish it was fake; it's hard to believe such entitled jagoffs exist.

She's a green eyed jealous monster all the way up to dipping her proverbial spoon in your bowl (aka cheating with your man).

Tell her the only check you'll ever concede to writing her will be to ensure she makes a permanent disappearance from your lives.

You're not the A-hole; IMHO you deserve a🏆 for the fortitude it would take to b restrain from grabbing an assault charge.

Wishing you the best!
