The only thing I perhaps could add to Neal's excellent advice would be to be a bit careful when watering. Preferably water from below and do not let any moisture stand between the stems and the tuber as this could cause it to mould. Also for the same reason it's best to carefully twist the fading flower stems away, don't use scissors as the stumps left could mould.
While not all Cyclamen will appear to go dormant in summer, you still need to be extra careful not to over water at that time as they do remember their origin. I remember throwing one out under a bush, forgetting about it the whole summer, no water more than what little rain it could get and then one day in September I saw it blooming again.
They are so beautiful flowers, but as Neal says they unfortunately don't agree with warm indoor temperatures. I used to carry them down in the cold cellar each night to make them grow better during the winter, but that gets a a bit tedious after a while
