Congrats bro!
I'm gonna get a lot of flack from getbiggers... but I genuinely believe getting married was one of the best decisions I've ever made in my life (I've been married for 6 years and have known my wife for 15 years), things between us just continue to get better and we are more into each other as time goes by.
Marriage is not for everybody, and if a person is genuinely happy being single, then they should just stay single (nothing wrong with that).
