affection
Your question is contradictory. "What if you love someone and she loves you back but she doesn't?" ...Clearly the answer would be that she doesn't really love you, and you know this, as you stated "but she doesn't."
The common term for it is "unrequited love".
ask them out.. Haha lol!
make a move!!! NOW! if you are lucky enough to have that happen, then hurry up and ask them out!
Say to him that you love him and wait for him to say it back. You'll feel it when he loves you back.
it is a strong thing to now if someone loves you it is caused by your fellings and if you love them they will love you
If someone loves you all they want to do is be around you and talk to you constantly. They will do anything to make you happy.
If she shows you affection
the guy tells you
When you're in love you feel so good because you know that someone loves you. And you know that you love someone so you're not lonely and desperate.
If they don't love you back already then I don't think that ther're really your true love. You can't make someone love.Thenfind someone that loves u.
talk to Them
