A person needs to feel good about themselves and happy in who they are as a person, if you do not know what you want out of life, your desires your hopes what can you bring
That's a "big 10-4"! If you can't be happy and content alone, why put your misery on someone else. I had to learn this by going through it. After a miserable 8 year marriage that finally ended, I knew what I wasnted and didn't want out of a relationship before I ever started the next one. My wife did the same, though she was single much longer than I. Just today, we had someone say to us after finding out we've been married 10 years this year, "Wow, I'd have never guessed. You guys act like you're still on your honeymoon." That was our new doctor who just met my wife for the first time today.
The difference is incredible. My two marriages are like night and f***ing day!
