First of all, have you seen Ken Singer's excellent article about disclosure and confrontation here on the site? It's very good and will give you some orientation and things to think about. Here's where to go: http://www.malesurvivor.org/ArchivedPages/singer3.html
One thing I think I can see in your two posts in your thread here is that you are not really ready for a confrontation yet. It may be something you need to do, but I would suggest you prepare for it emotionally and go in with eyes wide open, otherwise the result could be further harm rather than positive benefit.
If I were in your position (and I'm not - the man who abused me died years ago) I would be thinking of the following. I would be asking myself what do I want from the confrontation? Do I want to shout and accuse? Do I want reconciliation? Do I want an apology? In sum, what the hell am I doing - why am I going down this road?
And if I get any of the things I want, how will that help me in my recovery? Get a bit selfish and ask "what's in this for me?" It takes time and energy to prepare properly for a confrontation, so it makes sense to ask if what you want from it is really stuff that you need.
Then I would ask myself how I would feel if the confrontation goes badly. The abuser could deny everything. Or he could say he only did what I wanted. He might even say I started it all. He might tell me so what, get over it. There are all sorts of negative possibilities, and how would those affect me if that's how the meeting goes?
Basically, bro, look at this as a huge investment of your emotional resources. Ask yourself how great the risk is, and then, are the possible benefits worth that risk? Put yourself first, think of what you want and need, and then plan with that in mind.
You may find that you don't really need a confrontation after all, and that would be okay. It's not an act of cowardice or weakness to turn your back on the prick and decide he's not worth another moment of your time.
