I can definitely relate to this. When I was on myspace and Facebook a few years ago, I would unfriend then friend them back or block. It did bother some people and others not so much. As for you trying to make amends with you friends, I can also relate to this. I made a thread about my situation a few weeks ago. I tried to reach out to my female friend 2 weeks ago and again last week but she hasn't responded. I'm sorry that your friends aren't willing to talk to you or mend things. It does indeed hurt. Hope things work out for you and your friends.
