It is not time for plan B right now. Plan B is only to be followed through with a great plan A... and frankly my dear, although it's understandable, you took a few steps backwards by showing him how upset you were at resumed contact.
Ideally, you would have showed no emotion to your H upon his confession, EXCEPT gratitude for him telling you. THAT is the kind of action that blows the mind away from the WS. It makes them make "double takes", and re-affirm that you have changed, and for the better.
As ark^^ said to someone else recently, "you've fallen off the plan A wagon, and it's time to hop back on again". This applies to you too.
Although you cannot take back your actions from last night, you can at least be the better person (plan A, remember? <img border="0" title="" alt="[Wink]" src="images/icons/wink.gif" /> ) and apologize to your H for reacting the way you did.
Yes, HE should be apologizing to YOU. There is NO DOUBT about that! However, he's not "there" yet.
Recovery is HARD WORK! It's one of the most difficult things a couple can endure, but yes, the end result is fantastic... AS LONG AS BOTH SPOUSES WORK TOGETHER AT IT.
If you are concerned that your love bank is depleting rapidly and is nearing the point of being in the red, then it would do you good to start making plans for a plan B. Gather information... visit a lawyer, find out your rights, figure out your boundaries, and talk it over with folks on here on how to best implement them (that's something you should do anyways, plan B or no plan B), etc.
Hopefully more will give you some input that might help you along.
