How to show your friend your place in the relationship
Try socialise more with other people than your friend, it's not that you should break all ties or sumthing but just know what happens around you apart from your friendship.
Start being secretive,, stop being an open book with your friend.
Reveal secrets from time to time, making your friend realise that you also have a life apart from him.
Really have a life apart from your friendhship with the "problem friend". It would make you feel better too.
The basic thing is to make the "problem friend" realise that you can run smooth without him too. This would automatically pull your position up to the level , because friendship means both people on the same level of self-respect or dignity or whatever.
DO NOT go overboard, this is a sensitive issue because you don't want to break the friendship but just attain the same position you had before the "problem friend" started to supress you.
