friends help: SO I have this friend, we’ll call him Jay. - Help.com

You could try to still be there for him. Life might never be the same as it used to be.
That doesn’t stop you from telling your friend and re-sharing all of the good things that you remember, about you former relationship.

This might in fact get your friend, into remembering a very wonderful relationship. It might even make him want it back again.

I am sorry for the hurt you are feeling, there doesn’t seem to be a cure for this. Except that time will help you to accept, that something beautiful is no longer available.

It is up to you, to decide when it is time to move on with your life. When you are ready to find other things to make you happy and to forget the past and move on into now and the future.

You’re saying that he’s doing a lot of drugs… I don’t know where you live, but in most places that is illegal, and usually illegal things are bad things. Maybe something have happened to your friend that he hasn’t told you. Maybe he always wanted to be somebody that he didn’t think you would have accepted him to be. Or maybe he was sick of his old life and wanted to start a new one, breaking up with everybody from that life. Try to see things from his point of view.

I think you should try to talk with him and at least ask for an explanation to his behaviour and tell him how you are feeling. If he really want to move on, then you have to accept that, even how heartbreaking that may be.

I wish you all good and hope that it will work out between you guys.

I suggest you try to speak to him again. Tell him how much your friendship means to you, and that you will definitely be around to help. Listen to the response. If he just wants to talk, listen. If he wants help and doesn’t know how to go about getting it, show him. Otherwise, let him take the initiative. Hopefully, later on, he’ll turn to you for guidance. If not, then accept and move on (as hard as it sounds). One cannot change how another thinks/feels/etc.
