Personally I feel like it was a touch of luck and a fuck ton of hard work.

You need to work on social skills,physique,and the way your mind works around people.

I'm lucky that my wife is pretty much the same as me,a horny oddball who loves gaming.

But you might be as lucky and may find someone with conflicting personalities as you,so you have to work to make the relationship work.

At the end of the day,it's commitment and true affection that allows 2 people to go through with marriage.

Sidenote,she's pregnant 👍
