I hope my friend takes what I've said to him ok. He might get mad because he can get quite immature when his feelings are hurt. I am bracing myself for that. Or he might just get very cold and withdrawn. I'm sort of hoping for the best that even if he first reacts really badly, or if there is some distancing between us, he goes away and thinks about it a bit when he calms down and we can be closer again when he has some things sorted out. I do know that he's the type of person who doesn't do much self-examination unless he has a shock or there is an immediate threat that he's going to lose something, like an important friendship. Although I did emphasize that I want to stay his friend and that's actually why I'm telling him all this, but I really wouldn't be that surprised if he takes it badly
I know there are all kinds of different friendships out there. You may have some friends who you spend more time having fun with, others who you have more intellectual discussions with, others who you discuss your emotions and problems with. A mix of all of those is by far the best and healthiest but most friendships will be more weighted in some direction or other.
But one thing I know about myself for sure, partly through painful experience and partly through studying personality and typology and the like, is that I have to be more assertive about my own needs, and to tell friends when they are trespassing on inappropriate areas, using me, etc. It is sometimes essential to talk to people, even if it's hard and painful, before all the resentment and damage buildings up and explodes.
