Quote From: lovelandMy boyfriend's sister and I have been friends for about 4 years and we have worked together off and on. Currently we both work for her uncle. Lately she has been very rude and just out right mean to me specifically. We had been discussing the possibility of obtaining grants for the purpose of starting a business together. A few days ago she was complaning about money as usual and made the comment,"Well my dad said he was going to let me run my own little resturant....." I heard nothing else, I didn't want to hear anything else. I couldn't believe after years of discussing this she just drops me! Since then I just can't quit thinking about everything I have done for her (Mostly I regret giving her a dollar of my payrate when she was moving out and wasn't going to be able to get a raise) and how she doesn't deserve any hand outs when she can't even appreciate them. I've tried to igonre her, but it's hard she lives right next door and is always asking her brother(my boyfriend) for something! How am I suppose to keep myself from saying or doing something I'll regret? 
You can keep yourself from saying or doing something you will regret by continuing to keep in mind that you are the "bigger person".... Do not allow this person to have your personal power... When you allow someone else's behavior or attitude towards you p*ss you off, that is giving them your personal power.
You considered starting a business together, but you didn't, and its a good thing because now it is obvious that she doesn't communicate effectively with you. That is the foundation of a business relationship! You have regrets... but you were doing what you thought was best at the time, and now that you know better, you will do things differently. Someone said this to me a long time ago: "The best revenge is living well." Its the truth! You say that you have tried ignoring her, but it doesn't seem to work. It must be hard because she lives right next door, and she is your boyfriend's sister, after all... This will be tough.. but you can do it. You need time. With time, you will come to view what has happened in the past with a different perspective, and you might even come to feel sorry for her. How sad that she gave up your friendship for some reasons that you have no clue. How sad that she takes from others and doesn't know how to give back to the world. How sad she doesn't know how to appreciate what she has. When you see it like this, you are LUCKY to not have her as a friend any longer. I wish you the best, keep your chin up!!
