No you can't and you should never try to.
If you love someone you will love that person for who they are. If you love that person you will not try to change them.
Try and find someone else that you can love that will love you back.
If that person is your friend then tell them that you love the person they love. If they are your real friend they would understand.
Love is not forceful, and love gives without looking back. Love the person and be supportive, talk to him and try to improve the person, one day it will hit on the person that this might be love.
First start off by telling them , that yeah they are important to you , but they can't change who you are. You are your own person. If they don't listen being in a relationship with them isn't worth it. You want someone who YOU CAN BE YOURSELF AROUND. Hope I helped :)
The best way to find out would probably be to try and ask them. Nobody can know exactly what another person thinks or feels.
I would marry the person and see if it works out and if it doesn't, I would then get a divorce. Don't have any children with this person until you think you can both live and love each other. Or try living with them first before marriage. The person you love may not really love you back, people change.
Try to get to know the person. If he/she makes fun of you, tell them to stop. Or, ow do I put this, if he/she is really mean to you, maybe look for someone else to love.
You do nothing. You can not make a person love you and if you continue to try it will seem that you have a problem and are obsessive. Just stop and meet someone new.
Just try hard not to think about that person think about something else happy times ;]
i think you should spend ur time with someone u love and try not to tell that person.
It's likely that this man can love someone it's just that he doesn't want to or that he hasn't found the right person yet. If he doesn't love you - well, you can stick around because he might end up falling for you but don't try to change him because it won't work.
