if he is as great as you describe, then hes really worth your trust.  ask him straight out.  because theres no future if theres not trust.

Just wait for the future and see if you two will gonna be married. If you do, he's really the one.

You should be able to tell since your already dating him. Guys usually don't go out with girls they like unless it's on a blind date or something. So everything should be ok.

Yes, ask him.  That's the only way to find out.  If you know you'll spend the rest of your life with him, why not risk knowing sooner?

ummmm talk to him. you'll know after talking to him for a little while if he is and if you still are also.

if he feels he's financially and emotionally ready to commit with you at the next level...also, if he feels that, "she's the one!" thing...and that's it!

After two years together I think down deep you know this answer better than the rest of us.  No matter how good a relationship seems, how well two people get along, how much they have in common, there still has to be that extra something that can't be fully explained for it to be true love.  If you have that undefinable feeling and you can look into your future and always see you two together, then I think it is a pretty good chance that he is the one for you as long as he feels the same way.

Its hard to know for sure but one thing you definitely need is time. Don't rush into anything.  After a while, if you can't see your life without them, and you want them and only them then he's the one.

I think I knew by our third date. If you are not sure and you are questioning it then hes not the one. don't do it just because you think he might be make sure he is.

You can never know for certain unless you walked in on him..  But if you have a feeling that he is and you aren't usually paranoid or prone to jealousy, then something is wrong with the relationship.  Whether or not he is cheating.

if he cares for u and if he can do anythin  for u,then he is the one for u and if he is not proposing u should.

when he goes out of his way just to be with you and just to please you...when he compliments you in a sincere manner about your personality...when he is constantly present in every important occassion or activity in your life...when he cares for you, your family and even your pet..lastly, when he treats you like a princess..\n\n(3 or more of these scenario should be enough for you to know that he's serious...lucky girl!)

You can't know for sure.Only time will tell.There is no way to be 100% sure someone loves you.You will just have to trust that it is love or leave it alone.Love is something that cannot be defined;it is something that can only be felt.I wish you all the best.

Do you enjoy being with him? Do you two have a lot in common? Do you find yourself doing things for him you won't do for any other? Does he return the same affections? Feelings?  Is there talk of you being the one he was looking for? Then these may be clues that you have found the one you're looking for and the most you can do is see where it can lead. Good luck!

you don't. but then again, you don't know that he is. if you would have a reason to suspect it, then your relationship has underlying issues of trust.

your the only one who knows if he's the one for you. just remember that some ppl say stuff they don't mean when the are mad so, don't hold that against him.
