Like others have said I think its always important to analyse what you are hoping to get out of it - and then preparing yourself for the likely result of you not getting it and maybe getting something you really don't want instead. When I am contemplating confrontation I write down every possible reaction and leave space for reactions I can't even predict. I then analyse the potential harm of any of the negative and unknown ones with the potential gain of having spoken out and feeling more powerful. What I don't allow myself is going in with expectations as that is a huge disaster and pain inducing situation waiting to happen. In truth when I have done it and it went as badly as I predicted I did feel more powerful but I was hurt as I don't think that the secret hope can ever be fully quelled.
If he is a normal variety of bastard and didn't realise what was happening to you he may well feel guilty for not knowing, despite not feeling bad for his own appalling behaviour - but even then he may well not share that with you in a helpful way if you look at his mo.
