Karen - and Apachedove,
A belated and sorry welcome from me, too.
Reading your stories, I am completely shocked by your husband/partner's behaviours - the denial and anger is to be expected, as they are protecting something they are deep down probably quite ashamed of, and that guilt and anger will naturally be turned on you so that they don't have to own it. However taking things to the point of physical abuse (and in apachedove's case, an actual affair - regardless of who it's with) is
well beyond the point of an expected and acceptable response.
Usually I would recommend you try letter-writing, communication, counselling...but to be perfectly blunt and to-the-point (unlike me, I know!) I cannot suggest strongly enough that both of you find a way to get out of these situations - and fast. Get counselling for yourselves, and get out.
Ksmith said it all very well indeed. Your men need to either wake up and get help (something only they can decide to do) or choose to continue with their addicted lives in a way that is not going to put you at risk any more...and I suspect that when it's gone this far the only way they will realise they have to make that choice is by you leaving.
I hope I haven't been too harsh, but honestly these 2 stories really worry me...when a PA's denial comes to verbal abuse it's bad enough, but if it goes further to including physical abuse there is no reason for you to accept that position of a being stress-release "punching bag". I know it's almost inconceivably hard to contemplate leaving, even when they are treating you badly...I watched my father beat my mother as a child, and it was only after that that she managed to get the both of us away: she was - is - an incredibly strong woman who "simply" had her independence culled by his possessiveness and her self-belief knocked out of her by his verbal abuse until he got too frustrated and turned physically violent also. In our situation it was her love for me that made her realise that I was then in danger also so she had to get us out. So please, find a way to realise your value and stand up for it by leaving - if only because it's possibly the only thing that will get through to a PA in this stage of denial and give your relationship a chance of working, (but hopefully also because you know you deserve better than this!).
Love isn't supposed to be this way, you're right...but
is it love if he can hurt you that badly? True, unconditional love, to me, would have the ability to say "I'm sorry, I was wrong, how can I make it better?" when confronted, and make changes to ensure it doesn't happen again. So get out, get safe, then confront him...and find out what he is willing to do to change this unacceptable behaviour. This is not your fault!
Good luck
