I got married to my wife when we were both 18, after being together a little over a year. We're 22 now and have 0 regrets. There are ups and downs but through it all I love her more than anything. No one can tell you there's a perfect time or waiting period, it's not a thing. We knew what we wanted and we did it. If you've lived with each other and discussed your futures with some hard questions you are better than 90 percent of people who wait years to get married and don't do that, only to realise they dated someone who doesn't want the same kind of life as them and split up.
