Your sister may have what you would call bad behavior, but she is still your sister, and you have to be careful with the way you confront people. I think that you and your sister really need to get together, for a weekend or something and just spend time together, make memories together, talk, catch up, and let everything out. Remember that being hurtful doesn't accomplish anything. You can tell her nicely the things that bother you, and she can do the same, and you can both try to fix those things. Other than that though, you just need to accept one another, because you are sisters, and if you want to have the relationship, you have to give, forgive, and accept. I hope this helps and good luck.
