what do you do when your best friend dont listen to you..

Nothing, I think you did your part as a friend. It's up to him if he will listen or not. We cannot control people even we are their best friend. He has in own free will.

Hi, You really shouldn't do anything at this point of time. To be quite honest a person starts valuing good advice only when he is mentally ready for this. If you are giving him the right advice then surely someday he will realize it. This will strengthen your bonding even more than before. You really don't need to push hard. Everything happens for a reason and everything has a time to happen. Thanks. God bless you.

maybe your friend has trouble too, you can ask your friend first what happened with him. We must can see what happened among our friend. if they have problems, sometimes they doesn't listen what you say
