I have a lot of people who I use to consider friends, but nowadays my only real friend is my partner. I guess I've became so consumed with him that it didn't really cross my mind to make new friends when I moved out here.
Depending on your own situation, it can be difficult to realise which are friends and which are acquaintances. When something comes up and you actually find out who friends are, you can be surprised at just who are friends and who are not. In the final accounting, it's the friends you want to keep. Acquaintances come and go all the time, even if some of them stay longer. you'll also find that "friends" that get benefits from you, may not be friends at all. When the benefits end, so does the "friendship".
I don't trust people very much therefore I don't have very many friends. I like it this way though, I'm not much of a "people person".
My girlfriend and child demand most of my attention. I can always hang out with my brothers to do idiotic guy shit. Lastly I come here to placate my ego and converse about stupid shit... so I'm covered.
