Do you think people really value your own friendship?

I agree with Paul here. He screwed you over once, there's nothing actually stopping him from doing it again. Although, if you'd feel absolutely terrible turning your back on him, then be his friend but don't let him close like he must have been.

This. I actually did this with him and things weren't the same according to him. I just started watching what I said and keeping things to myself when I was around him.

Still the same attitude around others, but he started being more open with me. now that I think about it, everything we've said from then on out never got out to anyone we didn't already mention it to. The secret, I admit, was something big back then, but now as I'm older, it's still kinda there, but it's nothing big because it's more common now than it was then.

I'm testing him now. I said I'd "forgive him" and told him something he thinks is a secret but isn't really that big of a deal. If I hear any word of it from anyone else, then I have my answer.
