Well, your H(usband) will continue to have A(ffair)s unless he changes from betrayer to good partner, which is eminently possible for the vast majority of W(ayward)S(pous)es.
I'm very sorry you've experienced being betrayed, but I'm glad you found us, because I think you'll find help here.
First, as awful as you feel now, know that you can survive and thrive. You have to go through a lot of awful feelings, but you really can heal. Maybe you'll R(econcile), maybe you'll D(ivorce), but you most definitely can heal and to work to create the type of life you want.
IMO, you need to separate your healing from your H's and from your M's. You heal you. Your H heals himself. Together you (re)build your M(arriage).
Your say you'll start counseling next week. I'll assume it's M(arriage)C(ounseling). MC can be useful this soon after d-day IF the C starts with the A. That means starting by 1) helping you voice your thoughts and feelings about being betrayed, 2) gets your H to respond to you, and 3) gets your H to voice his own thoughts about his A.
Too often, however, MCs see an A as a symptom of a problem in the M - but an A is ALWAYS about a problem in the W(ayward)S(pouse).
That means the WS almost always needs I(ndividual)C - IC will help him change, if he wants to change and if the IC is competent. MC may help both of you - it certianly helped both my W and me - but the big payoff is IC for the WS.

You're probably still in shock. It's normal not to know what you want right now. I recommend not committing to anything until your mind stops taking you this way and that. If your MC urges you to make a choice before you're ready, that's a great reason to fire the C.
IMO, the best way to R is to define the behaviors you want to see, negotiate these requirements with your H, and proceed. If he behaves as he promises, R keeps going. If he doesn't, D may be your best bet.

I'm going to suggest a lot of reading. Start reading - if it's not congenial, move on to the next piece. If nothing below is congenial to you, come back and tell us why ... we may be able to help.
Here goes:
http://www.survivinginfidelity.com/healing_library/reconciliation/what-every-wayward-spouse-needs-to-know.asp - if this resonates with you, I suggest printing it off and giving the printout to your H as 'something you found on the web.' My reco: DO NOT tell your H about SI until you're sure he's on board for R.

You'll get a lot of advice from SI> Some will tell you what to do. Some will aim at helping your figure out what your best path is. We all have to find our own path, so I recommend giving more weight to the advice that helps you figure out what your path is.
