Lots of good comments in this thread. My two cents:
A lot of what your wife said is out of worry, focus on the worry and ignore the specifics. It is hard to be objective when emotional. Given the circumstances, her request to not ride is reasonable. Consider driving in for the immediate future - you may be able to commute again later. Life isn't that short. And you can always ride for fun - bike paths may be boring, but they might be the reasonable compromise you need here.

Whatever you decide, good luck.

Edited to add: don't worry about the work related comments much right now. Only you know how true that is - but her bringing it up is probably clutching for the proverbial straw to stop you from cycling in.
