I have a sister with a big heart, but an unhappy life and depression has overshadowed it immensely. To say the least, she stopped being my friend on Facebook because she couldn't not stop herself from saying something rude about pictures of me and my soon to be famliy (moved to North Carolina from hometown in Oklahoma). I disagree with just about everything when it comes to her, but know that I can be a negative person as well. We have pretty much decided that we are going away to get married, but I want a few friends to come along. This does not include my sister, mainly because I do not know which "sister" will show up. (she turns on this fake happiness, that is really obvious and unnerving). Bottom line is it will break her heart and I will be made out into the bad guy with my whole family. They literally take her side on everything because of how fragile she is. Any thoughts? I feel horrible, but do not want to go alone on my wedding just because she isn't there. At this point, I want to not invite my sister. If that isn't possible, we will just go alone, but this will stop me from sharing it with my true best friends that are truly happy for me.
