I think you've been very patient and understanding and your W and you sound as if you're both reconnecting really well.
Yes she made a bad choice and you may well have done the same thing given the circumstances.
Its hard to put into words what I mean about just going for it and being more forceful. I really don't mean any man should rape his wife or that no shouldn't mean no. Its just that sometimes a woman likes to be taken that step further. Its a fine line to tread but if she's giving you the right signals and then you back off that can be a turn off too.
It isn't realy fair that she thinks she has the right to dictate she'll only ML when she's ready and on her terms. Guess thats her boundary but doesn't mean you can't or shouldn't challenge it.
No matter how much better your relationship is zero sex is a deal breaker IMO.
