Sister silence

Your sister had no right to be angry with you when you left your unhappy marriage.It was also wrong of her not to invite you to her first DD’s wedding, but to invite your ex.
Perhaps you should have accepted the next wedding invitation, as it may have been her way of you getting together again, but I understand why you didn’t.
Don’t let all that stand in the way of your friendship as sisters now though, make the next move and say that you want to make peace with her and put it all behind you.
If it doesn’t work,then you have tried your best.Good luck.

My sister stopped taking to me in a similar situation like you I offered the olive branch and was rejected. She died recently and I was told by an uncle as the family were not going to let me know. I used to think of her daily and now feel sad at the wasted opportunities she rebuffed, Try again Silverlady and hopefully all will be resolved but like lemongrass says if rebuffed you have tried your best and move on :0)

It makes no sense for her to have been so angry about what was a decision personal to you - to leave an unhappy marriage.

I suspect that you now regret not accepting that second invitation; but it may not be too late to mend some fences. Write to her perhaps?

sometimes you just have to move on without them.My sister "abdicated" from the family when my dad died the only reason the rest of us could think of was that she didn't want to share in caring for our mother.My elder sister and I shared care for 12 years .
A few years later mum broke her leg and was in hospital for 8 weeks ,I wrote to my sister to tell her and ask her to visit...no strings attached I just thought she should see mum ,she didn't even answer the letter .We didn't have her phone number as she changed it when she cut ties.
.When mum was dying we tried again to get her to visit ,again no answer.
We managed to contact her daughter through FB and told her the situation.She still didn't come.
Mum died...sister turned up at the funeral with in -laws in tow .Stayed for the service and left.The few people she did speak to said that she told them she had a wonderful childhood but that she just didn't get on with mum .
Strange that ..she was the baby of the family and spoiled rotten .We dont see her except maybe in passing in town.She doesn't speak .Its sad but its how she wants it and we're used to it now 25 years down the line .
