I don't know why people would be telling you to dread it. That's pretty unsupportive. But getting married is kind of a big deal, even though most people treat it's just some relationship in which they can break up anytime. It's a lifetime commitment to someone, so as long as you're ready for that, then more power to you.
Awe I just got married two months ago and it's amazing! You should be very excited it's a big time in a girls life!! Here if you need any advice on planning or anything else! :)
For now..Excitement is how it all starts out. Haha, good luck!
