Hey all, my last post here was quite a while ago so if you need some context here's a link to that:

For the most part, tensions have subsided. I haven't really talked much with one of my sisters (which is normal for us), and one of them has actually been genuinely excited about the whole wedding planning process and is going to be in my bridal party. (yay!)

However, with the last sister there was recently an instance that disturbed me rather deeply.

I was at an event selling my products, and my sister just so happened to be there (she sells similar things). She walked over to my booth, gave me a hug, and asked how I was. My fiancé walked up to her and went in for a hug. She physically PUSHED him away, stuck out her right arm and said "just a handshake is fine, thanks". Immediately followed up with an ever-so-ingenuine "WOW, you lost a lot of weight, are you ok??" She then asked me if I wanted to take a walk.

I was so stunned I just went along with it. She then proceeded to completely ignore the interaction that just went down and made small talk with me. It was the absolute strangest thing I think I have ever experienced. I was so shocked, and I was in a situation where I had to represent my business so I was in no state to acknowledge how rude she was to my fiancé.

Then just last week we were at an event together and I happened to be set up across the aisle from her. All she said to me was "Well, looks like we're neighbors. Good luck today." I wished her well, and did not say anything else to her the entire day. It was obvious based on her facial expressions and body language that she was made deeply uncomfortable by my presence and wanted to be as far away from me as possible. So I respected those interpreted wishes.

The thing that you need to understand is that she actually does not know my fiancé at all. She has probably spent 3 hours total with him over the past 3 years. She does not know even the first thing about him, but has decided she does not like him for whatever reason. Which is strange to me since he has gone out of his way to be nice to her.

Anyway, after the first interaction I had decided not to invite her or her wife to the wedding. I cannot allow someone who disrespects my future husband to be around at all, no matter who they are. Life is too short, and I don't have time to allow people who negatively influence me in my life.

However, this is proving to be a difficult decision to make and I have been agonizing over breaking this news to my other two sisters. I know this will cause a riot and I've been delaying this conversation as long as humanly possible... I spoke to my mother about this and she actually does take my side and completely understands where I am coming from. At the very least, I have her and my father's support.

I worry that this severance of my relationship with one sister will thereby cause collateral damage to my relationship with the other two. I desperately do not want this to happen, but it is a very real fear. I am also afraid of confrontation and I very easily buckle under pressure when others are upset with me. I know my perspective won't be well-received and I don't know if I will be strong enough to hold up my end; I will be devastated if my relationship with the other two is also tainted.

I suppose the advice I'm looking for is... How do I stay strong and stick to my guns about this? Am I even doing the right thing?

TLDR: My sister is flagrantly rude to my fiancé. I decide not to invite her to the wedding. I have to break this news to my other two sisters and I know it's not going to go over well. At all.
