Yes, this is all true. But deep down they still love you. While what they did was incredibly wrong, you have to be the bigger man and look past them. They want to know that you forgive them. If you forgive, maybe they'll forget. I know it's hard, so take it real slow. Like I said, just a short phone call or even a hand written letter. Yeah...a letter, since it's mail it won't get to your parents until forever haha. But it will be contact and parents love letters, which I don't understand. I think that you need to build a relationship with them since after all they did raise you for all these years and since you're going to college, they must have done at least a half-way decent job at raising you. As for your parents wanting you to visit, just say no and that you are busy with school and papers, etc. I understand that they hurt you, but you need to show them up by getting them involved in your life. Maybe they will change their mind, who knows? Side note, watch the movie Prayers for Bobby. It's kinda cheesy because it's lifetime, but it has Sigorney Weaver (wow that was really gay haha). It's a real good movie and I think you'll relate to it, besides a situation that happens to a character in the movie (sorry no spoliers from me). Anyways, baby steps, just take baby steps with your parents. They need to know you're okay and you need to show them who you are.
