Hi Irondork, Resentment and anger can eat us up. Over the years, for one thing or another I've allowed it, too. Being angry has its place and can do us good - for a while. It took me a long time to realise that over the longer term it's wasted energy.
Try to remember - you are the free one - you can rise above their petty, childish games. They're spiritual retards in mental and emotional chains, being told what they can do, what they can't do - and what they must do. It took me a long time before I came to feel sorry for them.
Time to move on in your life and do the things you love to do, and meet new, better friends.
Best wishes from Flossycat.
