This amaryllis was a Christmas gift. It had beautiful flowers which have since died, leaving a green plant with huge 30" leaves. I've read the instructions for care, but I live in Central Florida and the temperature never gets cold enough for the plant to go dormant like the pamphlet says.
Should I just continue to water it, and hope it blooms again at some point? And does it need to be repotted? Its getting really big and i don't want it to tip over! Thanks in advance for any advice.

yes, water as usual, it will bloom every year, +/- . You can repot it if you want, but better to add a rich nitrogen fertilizer.

Plenty of growers of Hipps like myself let the bulbs do what they want as far as dormancy, and reblooming schedules. The industry has decided we all want them blooming for Christmas, so they take special effort to force bulbs that we buy to that schedule.
In my area, they can't stay outside in winter, so a winter dormancy is actually for my convenience, in a way. It's easier to store them inside as dormant bulbs in their pots, than as a houseplants needing light, warmth and water. I'm of the opinion the bulbs probably don't require dormancy, but are well adapted to it. Mine spend the summer outdoors, then as late summer approaches I let them dry a bit. If they decide to go dormant, and most do, I store them in an unheated dark basement room until they 'wake up.' If they decide not to go dormant, as some do, I'll treat them as house plants, resume watering, and they bloom (or not) as they want.
Your bulbs will need all the light you can give them now, and mild fertilizer through the summer, as now they are rebuilding the strength for future blooms. If you move them outdoors, remember to harden them off as they aren't accustomed to full summer sun and wind yet.
[***Edit: "all the light you can give" means indoors! Outdoors, mine get a little sunburned in full sun, so others in Florida should advise you on light requirements outdoors in Florida summer sunshine.]

In your area, you might have the option of leaving them outside all year- perhaps keeping them in large pots or in a garden bed. I'll let others discuss that.

Thank you. I appreciate the responses. Guess I'll just keep caring for it like a regular plant, and when it blooms again it will be a nice surprise!

I've been off the internet for a few weeks so just now saw this post. Your plant looks very healthy and the bulb is planted at a good depth. To increase stability of the pot, You can plant it in a slightly larger pot, or leave it in this pot the first year. Put it where it doesn't get the intense heat and sun of the late afternoon. My potted amaryllis are on the east side, about ten feet out from the house, so are in shade after 2PM. Water and fertilize it in the summer. You can bring it inside if frost is imminent in the winter, otherwise it can stay outside or even be planted in the ground, as long as it isn't getting overhead irrigation from a lawn. Mine are pretty much watered by our frequent summer showers. It will most likely bloom again next April. Blooming is a function of increasing day length and increasing moisture in the spring. I think you will do very well with this particular bulb.
