If you care for their happiness and well being more than yours, If they make you feel good when they are around or just when you hear their name. If you want to be with them as much as possible.
ANSWER:
I think I will let you ask the man I married with your question, cause it happened to him. I will share to you what my experience is, all the sign was there, and if you do ask this man I married, he will tell you that he was only infatuated with his ex mistress. This were what I noticed from him, as follows;
1- talking on the phone 24/7
2- Being with his mistress everytime on her days off
3- going out on a date, even very late night
4- exchanging email
5- going to church together from her town to our town
6- and the romantic of them all, he can not start his day without hearing her voice,
and he can not or will not sleep without calling her.
well its just for people that are bored and really love someone and just wanna know..or if someone is really paranoid and just wants to see how the results would come out
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."
"i love you"
You can learn to love someone by getting to really know them.
It is really impossible to say hi ilove you then later on someone would love you too. There must be a process on it.
Tell them
You have to know it in our heart. there is not "text book" answer.
It's not something you can go around asking a website. You have a feeling inside of you that says, "I cannot live without this person." You will know when you are in love. Also, once you really love someone, you never completely get over them.
Answer You make the effort to get to know them - really get to know them.
Yes.AnswerAbsolutely.
if you really someone you let them know and tell them how you feel and see if they feel the same way
If you want him or her to be happy. even if it's with someone else.
