Hi guys...I don't usually write blogs and stuff. English isn't my first language so please bear with me. I have been bottling up my feelings for a week but i can't anymore. So here it goes a guy confessed to me (lets call him C)but I rejected him last year and in my group of friends there is this new girl ( lets call her A)she likes him even when she has a boyfriend but they broke up for some reasons.A starts claiming C is hers when she found out he confessed to me and my friends help both of them to meet up after knowing that I don't mind. At first C didn't want or even like A but after pestering him to go out with her  and setting his profile pic as her timeline cover without his permission, he agreed but they broke up since her ex boyfriend and C are friends and her ex told C about how A came in the way of her ex boyfriend's previous relationship with his girlfriend and told C how A will take revenge by going out with one of his friends. After C and A broke up she was completely restless and was pestering me to give my Facebook account that has been deactivated for like four or five months and I gave it to her since she was my friend and I trusted her..when she was using my account she made me look like a pathetic person that knows no boundary in front of him.she was telling him to meet up with her,she was crazy about him and other pathetic stuff using my account and then C blocked my account being fed up thinking that I was too much but it wasn't me he was talking to it was her!! I even send him a screenshot of her asking my Facebook email and password but he still keeps blocking but he doesn't block her..I don't know what to do. I am feeling so betrayed.
