Back to square one...
Am I to suck it up, keep on w/ another Plan A?
Only if you still want to try to save the marriage.
Do I not let her know my hurt?
It probably won't have much effect on her, but might make you feel a little better.
This isn't uncommon at all, 2B1. Very often a WS will go a short time without contact and then relapse. This might happen a few times before NC sticks.
I haven't read your sitch. Can you link it?
Dr Harley suggests that men should be able to really do a decent Plan A for up to six months and women for about 3. The difference is primarily because men rise to a challenge a little better and are more competitive to begin with (It has to do with testosterone.)
Just so you understand that recovery is a very long road, seldom does a marriage recover in under two years of both WS and BS working together on it. It can and does take much longer in some cases. So this is what you have to look forward to. Only you can decide if it's worth the effort, but if you are going to fight for your marriage, you pretty much have to put your own needs, wants and desires on hold for quite a while, even if the A ends right away.
BTW, your comment that Plan A was successful suggests that you don't fully grasp Plan A as of yet. I only say that because Plan A is all about changing you to be a better alternative than OM. It isn't about fixing the marriage or forcing NC or even ending the A. It's about you and what you do, not what she does or doesn't do.
By meeting her ENs and avoiding all love busters, you are making your own balance in her love bank grow and in so doing, raising your status above that of OM. Unfortunately, she is only accepting a small part of what you are depositing, so you have to work overtime to get the job done. And to save your marriage, you have to be willing to do this for quite a while. In fact, you pretty much have to make the changes to your self that can last the rest of your life, since you must meet her ENs and avoid love busters as part of the MB way of creating a better marriage, not just for a short time in order to end the affair. The difference is that during Plan A you do it without expecting anything in return from her at all and once in recovery, you can expect that she will be willing to reciprocate at least in part.
