Well, i may not date anymore, i'd rather be one night stand or friend with benefit, but when i actually thought i found "the one" a large number of people gave me the same news that she was cheating, i never believed it until i catch her kissing someone else, at that time i noticed, even "the one is going to cheat" but it all depends on what you want that person to be. If hey have what you look for then maybe they are the one, there's never a 100% chance of finding that kind of person mate, sadly, true love is already dead. So i'd advice you to not waste time, concentrate on your future. The decision is entirely on you, mate.
forget all that bull. im sorry but all those answers are truley rediculous. You will know when you have found the "one" i promise. There will so much love and loyalty in your heart that you wont understand. He/she will be the only thing that crosses your mind.when your having a bad day you will want them and them only. you will know they are the one if you can picture yourself growing old with them. you can picture your life with them 10 years down the road. They are your rock and they are your shoulder. you lean on them and they lean on you. life without then just wouldnt be life. i can tell you havnt found the one yet cause if youdid you wouldnt be asking that question. but just wait they will come:)
