Basically the universe will go on expanding for ever , but the everything will become more and more spaced out until every atom is so far apart it can no longer interact with anything else.
We don’t have to worry about this for a VERY long time – current guesses put heat-death at around 1 with a hundred zeros (a googol) years after the big bang.
The big bang was 13.7 Billion years ago, so we are around 10% though the maximum age of the universe at the moment.
I have no idea. Hopefully it won’t be our fault in some way. I don’t know if there is any evidence behind the idea that eventually the universe will stop expanding and will start coming back in on itself.
