I agree, your plant appears to be a Guzmania and it does appear to be at the end of it's life; nothing you did wrong, it's just the nature of the plant. Sometimes they produce small pups at the base of the mother plant that can be removed and potted up to grow on for another cycle. https://en.wikipedia.org/wiki/... http://www.bromeliads.info/guz...
