The best way to find out would probably be to try and ask them. Nobody can know exactly what another person thinks or feels.
they dont want to talk to you or they simply dont have there phone around them
One thing you can do is: Probably to work around it until they like you back.
Yes and no some people dont believe in karma others do so it just depends but if your mean to someone it could come back to haunt you.
just tell them you dont feel comfortable with the things they say and you need them to stop because you cant be around someone like that.
Try to get them to like you back or move on
just be yourself and people like you for who you are and i someone dont respect thatthen dont change

Answer Unfortunately this happens sometimes. You have to move on. There is someone else out there for you who will love you back.
'but it isn't the same if they dont love you back'
if your asking wiki answers than you dont have much hope
You hurt them too badly; they dont want you anymore
Find someone new. You can not change another person's feelings.
