I think a lot of people you know will be excited for you. It's not like you've both been married and divorced 5x before and have known each other 2 months. You have a stable life, have been together enough time people are probably getting eager for "when", and it's a first marriage of a happy young couple. What bitter old hag wouldn't be excited and happy?
Then again, just because there are some bitter old hags out there, be aware, some people won't care. O well, they probably aren't people your particularly close with anyways. The people that matter in your lives will probably be thrilled and very excited your finally making it official.
My family has a long history of marrying young, brief dating before marriage (but for the most part, long, happy marriages that result). My husband and I were together for almost 5 years (moved in together a few weeks after meeting, I was only 17) before we woke up one day and decided it was probably time to make it official. Our families were ecstatic because they thought we would forever be girlfriend/boyfriend, as we were the first on either side to wait more than a year before marriage, and being as purr families were both religious, they did not like us living together out of wedlock.
