I have had a Chinese elm about 12 inches high for the past two years.
Last year I left it outside until the leaves turned color and fell. I
then put it in a cool but not freezing area for about six weeks and
then brought it indoors, where it soon began to leaf out again. It
spends the summer outdoors. This year I was caught by surprise with a
sudden cold snap in November. The tree's leaves never had a chance to
turn, but the sudden dip to below freezing temps just killed all the
leaves (this happened for most of my outdoor plants, not just the
bonsai). I brought it indoors right away.

I bought this tree from a bonsai master who told me it could be treated
as either an indoor bonsai or an outdoor bonsai if protected from very
low temps. I'm beginning to worry however that I still see no signs of
buds after more than two month and a half months indoors. Some of the
outer twigs have died but when I cut one a little closer to the trunk,
they are all still green under the bark so I know it's still alive. But
could the sudden frost have been too much of a shock, or do you think
in due time the tree will start to leaf out again? Should I consider
re-potting soon in the hopes that will save it?

I wouldn't repot, you'll just stress the plant more.
