Hey! I am Christian also. I do know that many congregations have a minimum rule of 6 months dating and 6 months engaged before they will agree to marry you, so this is a discussion that you might want to have with your pre-marriage counselor. I’m not sure when you got engaged, but it sounds like your original timeline fits this criteria.
Definitely don’t let your friends (or anyone) dictate your marriage or your plans as a couple, but at the same time, if your Maid/Matron of Honor has some concerns about the relationship, do hear her out. That doesn’t mean you have to do what she wants, but if there are any specific concerns that she has, it may be helpful to consider them.
If you guys do decide to move up your date, there are some things you’ll have to think about. First, you’ll be planning the details of your wedding (and having to deal with moving the date for everything you might have already booked), moving, and adjusting to living with someone new (it’s all fun and games until you realize all the little annoying things they do…or won’t do), all while trying to finish up school. While it’s exciting, it’s A LOT of responsibility and pressure to handle all at once. You might also get questions from nosy or judgy people as to why you’ve moved up the date (aka: they’ll think you’re knocked up and having a shotgun wedding). Obviously who cares what those people think, but it is something you might have to deal with. Also, definitely keep in mind the unexpected. Will you be ok financially and in your relationship if you can’t find a job in your field immediately after you graduate? What if you get pregnant right away? What happens if your Darling Husband gets laid off? I’m not saying don’t do it if that’s what you really want, but these are definitely some things to think about.
From personal experience, I’d say that of the friends, co-workers, and church acquaintences I know who got married in their early 20s for intimacy reasons, maybe like 50% or more of them have since gotten divorced before age 30. That said, I’d say that there are a lot of factors that go into this, not just the number of your age. Many of them got married before they were financially stable. Some of them got married before they realized that they hadn’t exerienced enough different relationships and other people to understand what they really wanted…and didn’t want. Some of them found out things about their spouse that they didn’t see before they were married (they were an alcoholic, actually attracted to the same sex, had different life goals or their goals changed, one person wasn’t good at dealing with conflict or willing to work on it, abusive, cheating, etc. ). The point is, there are a lot of factors that go in to determining if a marriage will work. Does time make it easier to figure these things out before you commit? Yes. Does age and experience make it easier for both people to figure out who they are as people before they commit? Yes. Do people who get married very young or very quickly always end up unhappy or divorced? No! But, everyone is different, and your pre-marital counselor will be able to help you discuss and work through many of the things that could potentially cause issues in your marriage.
Hopefully this gives you guys some things to think about and discuss as you make your decision. Good luck!
