Congratulations!
I got married at 37. Much the same as you, I've always been introverted and awkward. In fact, your story reminds me of mine, by a lot. My wife and I have been married now for 20 years. I'm sure you two will be very happy together. Just focus on being good for each other and you'll do well.
Oh nice to know it's not just me! Tbh I just see it as not bothering with the first, statistically very likely, failed marriage at a young, naive age lol.
I think I have all the tricks of the trade to make things work out now =D can't wait for the next 20 years!
It is true, if we get married too young, then it raises the chances of a failed marriage. You were wise to wait. Good luck and God bless!
