I think you need to deal with all the boundary crossing going on.

"I feel you are being extremely disrespectful of me and my boundaries. If I find you have communicated with someone from my life by getting their name off of my Facebook page again, I will have to unfriend you on Facebook and make it so you can no longer see my page or communicate with me that way."

To Other Friend you say, "Please to not call me about someone else's concerns. I love hearing about how you life is going but I will not talk with you about my relationship with someone else."

Let your friends know what you will accept/not accept in your life, your boundaries and the consequences of their being crossed.

"Do not call me at work. If you call my work number again, I will get a cease-and-desist order to protect my privacy from you."

"I do not want to talk to you on the phone more than once a day. If you call me more than once I will block all of your calls and no longer take any phone calls from you."
