Oh yes, I do know what you are talking about! I had 2 best friends in college- they were like sisters to me. Well, we all decided to move in together, and I being stupid, allowed my boyfriend to live with me for 4 months. It ruined everything and my relationship with one of them. By the end of our lease, we weren't even talking. And I packed up and left and we never even said goodbye. I tried to apologize over the years, but I didn't have her email or phone number anymore. So, about 1 1/2 years ago, a former college friend suggested I add her as a friend. I wrote this long message to her, apologizing, saying I am so sorry for everything and then tried to add her as a friend. Well, she accepted my friend response, but never responded to my message at all. Never has once tried to talk to me or message me. I really expected a response after this heartfelt message I wrote. Some things you just have to let go of in life, and I can say, I finally got to apologize after almost 10 years and I am letting it go now!!!!
