if i were you i wouldn't wait for an apology, since if you have't gotten one by now you probably won't. you have to get on with your life and realize these people are probably happy together, you just got stuck in the middle. i wouldn't be jealous of them they should be jealous of you and that would happen after they see you get on with your life, there are a lot of fish in the sea and you shouldn't worry about it anymore, the person who broke up with you may even regret it after awhile, but if they do you you deserve better now anyway and have it in your reach to get what you want. you can find love again and you do deserve someone better.
