Honestly friendships tend to come and go throughout the course of the lifetime. Not sure what age group you are in, but this is rather common in the 20s.

Everyone needs people around them to support them in their life choices and be a part of their daily existence. Sometimes when we change or improve ourselves, the friends we once had no longer have the same interests or common characteristics as us and that is okay.

Changing over your social connections isn't always a bad thing, but losing your entire social network can be a little rough.

I don't think that its a big cause for concern if you are removing tight ties with people that aren't building you up or adding something to your life. As you kick out people on your board of directors that you might want to seek out new candidates to fill those positions whether its through school, church, vollunteerism or other activities in your community.

Plus you never know how things are going to play out, you might write off your friend right now in the moment but find that as time passes things change, people change and you can reconnect with him in a new way, perhaps standing on different ground.

Love yourself, stay healthy and be positive. Everything will workout.
