Kurt,
This problem of guilt is a huge one for survivors and I think we all have a tough time getting past it.
A big part of the problem, Kurt, is that you are now some years older than when the abuse occurred and you have changed a LOT in that time. You don't see things the way you did when you were a younger boy.
A little kid makes some basic assumptions about the world. He thinks that he cannot be horribly hurt, and he considers the world to be safe for him. He also considers that he is worthwhile and lovable. When he is abused all that goes down the drain. He now sees that he CAN be terribly hurt and that the world can be a very unsafe place for him.
Why is that, he thinks? Other kids all seem to be okay and happy, while he is feeling more and more confused and ashamed. He starts feeling alone and isolated, and when he looks at others and asks the question "why me?", his answer is that it was all his fault - he is to blame. Sometimes the abuser will actually try to encourage this wrong idea. He will tell the kid "you like it" (especially if he gets an erection or has an orgasm - in reality neither is uncommon and neither means you "liked it") or "it was your idea as much as mine" or "if you didn't want it you could have said no". Or the kid will see possibilities that he didn't see when he was little, as you are doing now when you ask yourself:
but why didn't you run away and tell everyone what was happening? why did you listen to him and let him do everything over and over even though you hated it and just wanted it to stop?
Perhaps the biggest thing that a boy looking back at his abuse notices is the fact that he DIDN'T TELL ANYONE. You put it really well:
when i went home each night from his house why didn't i tell?
You think that every time he did things to you, you had a chance to stop it by telling when you got home. You didn't, so it's your fault.
But you aren't the boy now that you were then, Kurt. You are older, for one thing. You are writing from the safety of your home, probably, and right now you don't have abusers in front of you. So of course you can think more clearly. A frightened boy being threatened RIGHT NOW doesn't think like that, especially if he is younger.
When I was dealing with this feeling of "it's all my fault" I was thinking of the same choices that you have in mind: I could have done this or that. But then I thought back to when it actually happened. I didn't think of choices or what should I do. I was 11, and what I did was freeze, feel myself being flooded with fear and confusion, and start crying. That's it.
As for telling, you didn't tell Kurt because you couldn't. It really is that simple. An abused boy blaming himself for what is happening quickly loses the idea that he is worthwhile and lovable; NO ONE would like him or accept him if they knew. NO ONE would believe him. He would be in so much trouble and be even more ashamed.
As this gets worse, bro, the boy's feelings about himself become so bad that he just doesn't care anymore. He doesn't think that he is worth any better than this, and he can even get to the point where he later thinks he was "cooperating" with the abuser. In my case, if nothing happened for a week I started to worry and wonder what did I do wrong last time?
But all that is just the behavior of a kid who has been totally wrecked by abuse. He doesn't have a sense of sexual boundaries, his self-esteem has been wiped out, and like every other kid he needs attention - in this case he wrongly concludes that the attention of the abuser is worth having. But who messed him up like this? The abuser did, Kurt.
You also live from day to day, and nothing is planned or makes sense anymore. Do you remember thinking "Maybe I'll tell tomorrow", or "another day"? By putting things off one day at a time the abuse can go on for years.
A lot of this bro, is just pure emotion, and that's why it all resists our efforts to think about it logically or "figure it out". What's logical about molesting children, after all?
This all gets very complicated and this post is already too long, but maybe this will help you as you start to see how it goes. The things I have sketched out here have been repeated thousands of times with abused boys, and as you talk about things and read here you will see this and will understand your feelings more clearly.
Kurt you end your post with some important comments:
i can totally see some of you guy getting mad at me for posting this. i can see you being like,"oh my god, stop whining, you know it's not your fault..." then again you have never said that before...maybe you'll understand.
No, sorry.

As usual, we will not be mad at you, and it is not a bad thing to raise the same questions over and over. They are important questions and those things NEED to be covered again and again until we understand them and believe the truth about them.
You say "maybe you'll understand". You bet - we have all been there Kurt! What you are feeling now is how ALL survivors start out. It will get better, you can get your life back, and we will be here to help you.
Much love,
Larry
