Hate myself for being jealous of my cousin's wedding?

I have always been my family's "black sheep" and have been treated awful compared to my brother even though I have done wonderful for myself in my career choice in my choice of a wife and all manner of ways in between. I have a beautiful 3bedroom 2 1/2 bath home my wife and I each have our own vehicles, we have 2 fourwheel ATVs, bought us a monster of a dunebuggy earlier this year and have done very well for ourselves. MEANWHILE my brother is a convicted felon has spent more time in jail than out this past decade and can't even seem to hold down a job or see a child that he fathered and never cared to even want to help with her. STILL my drug addict brother is the darling of our family. If you love him are still together and happy then to hell with what your family thinks you have every right in the world to be upset with your parents handling of your marriage but as long as you have each other it's the two of you vs the world. As long as your cousin didnt show the same ignorance and awful awful racism towards you I would say to support her in this time as much as it hurts but personally I would NOT go to the wedding. If she showed you and your husband respect and love during the course of your relationship get her a really nice gift tell her how happy you are that she found someone to make her as happy as you are in your marriage and you and your husband take that money you would spend on going to HER wedding and the two of you treat yourselves to a second honeymoon somewhere spend the entire time with some great wine and good food just the two of you and spend it in bed the entire time making each other feel how great you guys feel just being together and to hell with everyone who wasn't there for you :-)
