Congrats mate, I hope the partnership/relationship is never broken...!
Your 38 year made me think of the first time I said, I do, that was 36 years ago and I got 12 years out of it, I often wonder what happened to my first and unique first love since the age of 12 (married at 19) and while I was very matured for my age, were two things lacking, one was the maturity that only time brings and the second was the lack of having any support/guidance to the "bumps" a marriage throws at you, particularly at young ages...!
Lesson learned, deep scars to carry and after all this time, I wished that, things had done in a different direction, such is life...!
I'm not going to ask you what the secret is, I don't need to ask that question anymore, I got the answers as I got older...!
Keep it good, is well worth it...!
Cheers
George
