I feel for you, man -- really, I do. But I think you have to decide whether or not you can live like this, and if so, for how long. Because there's a very real possibility that this is "the new normal" for your wife.
There's an old joke that goes "I want sex 6-8x per month and my wife wants it once per month, so we compromised . . . we have sex once per month."
There's a lot of truth in that. The low-drive partner will always dictate the pace (or lack thereof) of the marriage's sex life. Each partner needs to decide what they can abide, and what they can't. Unless there's an underlying medical cause, or other marital problems impacting the SL, rarely do these things change much, in my experience.
But as I've said before, I may be the cynical "low test score" you want to throw out on this subject.
For the record, I don't think you're being unfair here. If your wife's primary LL was, say, "quality time," I don't think anyone would fairly suggest that she "just get over it" if you withheld quality time from her for six months.
