Is it normal that my friend is always ignoring my phone calls?

He might be like me and have a phobia of talking on the phone. He may be even more so like me and have a phobia of texting, which is what I had in the past. Even now, though, I still experience anxiety. Or, he may have tight finances and worries about jacking up his phone bill. You should ask him why he does this.

Always?

Either you call too often, or he seriously just doesn't want to talk to you.
STOP calling your 'friend' before (s)he really says something that will hurt you (its ironic that our 'friends' can hurt us more than anyone else could).

Maybe he just doesn't want to be your friend. That or they are like me and before use to get messages every other minute so spent all day on phone yet after people stopped caring about me I stopped caring and now I don't hardly answer at all. In fact most of the time my phones dead since I forgot to plug it in again and I just don't care anymore. If its on facebook they might be multi tasking. That or just take awhile to answer back. I have a ton of friends who stopped messaging me.

Your friend is hilariously awesome. Look. I was a teenager before everyone had cellphones. They started becoming common towards the middle of college for me. The idea that people know you have your cell phone on you at all times...you're attached to "apps" at all time and you're always "connected" at all times is an additional stressor to us. Your friend choosing not to feel obligated to keep contstantly in contact is probably wise for his own benefit. Leave the guy a message...and he'll call you back if he's not busy.

"When I was a kid" it was acceptable to call back as late as the next day...because you had to be at your house to first hear the message on your answering machine and then have time to call back which you couldn't do on the go. Cell phones have almost forced a false importance on phonecalls. Kudos to you friend. Think of this as him helping you be less needy.

At least you're not the only one that feels ignored. I've been in a similar position, and the best I can say is cut communications (remove/block his number, but not out of passive-aggressive behavior) and move on with your life. I don't know exactly what's wrong with your friend, but he's got quite a number of issues to resolve.

maybe he is reversing the trend of social media sites and creating anti-social media sites

There's a lot more to this story than you're letting on.

Are you and your friends jerks to him? Maybe this is his way of returning order to the universe without being confrontational.
