Getting married and not one congradulations...help?

Well, it sounds like u have done all the right things to prepare urselves. If ur gran is a pastor I am uming ur Christain also, and on that front, getting married is better than sleeping/living together. In generations past u'd be seen to be a bit long in the tooth by now! Ignore the critics, invite those who love and support u and have a happy and long mariage together. I got married at 20 and heard all the same stories, I think the biggest challenge is to grow together over the years, that was my issue 18 yrs down the track, we grew on different paths, but I don't regret the age I got married. Congrats!
