I need advice....

Ellie

I don’t really know where to start I just know I need advice and please don’t be rude or hateful. I love my sister to death we were best friends for so long and she’s my only sister but after she got engaged to her now fiancé she completely changed.... I strongly have always disliked her fiancé after having sever late night phone calls calming her down after he’s treated her like dirt and eventually cheated on her I just can’t find it in me to like the guy. She would always text or talk to me once a day now I’m lucky if its once a week and when she does talk to me it’s only if she wants something she claims to always wanna hang out but never makes the time but always makes time for her fiancé and his friends and family. I’ve tried several times explaining my hurt and feelings but it always ends with a fight and her blaming everything on me last night it got to the point that she said if I can’t like him I won’t be invited to her wedding or even be apart of it. She then she goes on to say how sh**y my husband is mind you my husband isn’t perfect but he’s far from sh**y. I just need some help on what to do and any advice.
