Unfortunately you can't force someone to get the help they need. When the idea comes from us it's also almost immediatly dismissed also. It's better to let them figure it out on their own, it may be the only way.
My W says something similar about getting help so I understand how frustrating it is. She says she doesn't need to get help because she can talk to her friends.
Accept what is, let go of what was, and have faith in what will be
