be yourself, if they liked you befor they'll like you again.
You can't really force someone to like you again. Why did that person stop liking you? If you know you might understand if they won't 'like' you again. If you don't then you will never know. All you have to do is continue being yourself, if they don't like you for who you are and how you act, then why would you want someone to like you for someone who you arn't?
Sure there is no harm in it.
Hypnosis, perhaps. You can't MAKE someone like you.
Yes, we are seeing it now with Trump.
Just go out with that person, and if you don't like him or her then don't go out with them again
No, but that does not prevent someone like him being born.
Someone can get an ex to like him or her again by showing that you still have respect for their previous choices. Give them their space but check up on them often and say hi.
It means you liked them the whole time (subconciously) and u should go out with him or her.
Most people who break up and get back together again will end the relationship again. Best to move on to someone who is more compatible.
You just know. I did. And so did she.. will never happen like that again.
You ignore him. Tell him he is being immature as nicely as possible and then walk away. If he is someone who really cares about you he will start being nice to you again. If he doesn't, then you don't need someone like that in your life.
Try and get over him by going out with someone else you like, maybe stay out of his way for a while to get over him then try and be friends again. Maybe one day he will like you but if not oh well
