Alot of people are saying im more better off being in a relationship but i am more happier being single how can i prove people who think im better off being in a relationship that im more happier being single?

You should stop looking for confirmation and validation from others in order to set up what should or possible can make you happy.

You decide your life and set your comfort zone. You don't need to prove anything to anyone. This is your life. It's nobody's business to see what you see, it's nobody's business to support you for what you choose. It's only your business to see your path and support your own decisions and stand by them. This is your life not theirs. Own it and don't waste the time you have got in this journey to convince others how you wanna live. As long as you are convinced. Nothing else matters.

You prove it by living your life and being happy. And not worrying about what others think.

Say this and it will shut them up  ...I've been single for a while now and I have to say it's working out ...I mean,  it's going very well ...I think I'm the one!!! :)

You are not in this world to live up to,

any ones expectations. But if some how,

you meet in the middle, its beautiful.

You don't.  I was single for years and enjoyed by own company. But if you want a come back..

"Really? Did you know statistically 40 - 50 % of marriages end in divorce?"

"I've fallen in love with the person I'll spend the rest of my life sleeping with...me."

Hang glider pilots spend a lot of time waiting for the right winds so that they can fly -- but they all agree that they'd rather be sitting on the hill wishing they were flying than to be flying in violent winds and wishing they were sitting on the hill.

Relationships are like that. It's a whole lot better to be single and happy than to be tied to an unhappy relationship.

Forget about all those well-intentioned people who want you to be "as happy as them". You owe them no explanations and no justification for your preferences. Just tell 'em to butt out.

Given your age, I am really surprised that anyone is suggesting that at your age you would be happier in a relationship rather than you would be by being single. 

You may or may not be, but I would never presume to suggest that you seek a relationship with someone.  Heck, your brain isn't even fully developed yet.

At any rate, just tell them while you consider a relationship to be possible and / or even probable in the future, at the moment you prefer to not undertake the responsibilties required to build and maintain a relationship with another person.
