Does it bother you if someone you are relatively close to ignores you?

It bothers me. I have a best friend whom I've known since 5th grade. The last couple of years have been somewhat chaotic for me. Now I don't make a habit of always reaching out for help, by any means...but in this case, just having him around would help. It seems like we've drifted apart and that makes me sad. I know things have been tough for him also, so I do my best not to cast blame. Still hurts. I miss my friend.
