Following on from a post I made on another thread.
I had major problems with a colleague from work a few years back. She befriended me very quickly and tried to make me one of her best friends, all the while she was actively trying to ruin my career behind my back. She did all this whilst smiling to my face and drinking coffee with me. Anyway turns out she was doing this to other friends and colleagues. I confronted her on it and she denied everything saying 'but can't we still be friends. .?' Err no! I had seen emails she had written and caught her in the act so to speak so I knew she was lying. So I told her we were colleagues and needed to maintain a professional working relationship in the workplace, nothing more. She ran off crying?? Anyway it was horrible. I soon found another job through an internal transfer and then found out she'd tried to sabotage that by stopping me going! All very weird couldn't get out of there fast enough. With hindsight I wish I'd put in a compliant but I just wanted to move on.
Until recently we worked in the same company but it's very large with multiple sites so managed to stay away from her for a number of years. However over the years i found out through colleagues that she was still trying to make trouble for me! I've thankfully left the company now so at least I won't have to deal with her nonsense anymore.
Here's the 
part...
She recently sent me a Facebook friend request! I mean WTF! Really??? Why on earth would she think I would want to be friends with her. I hardly ever use FB but there's no way I'd want her seeing what's going on in my life. I also suspect that she's been looking at me on linkedin. Social media I know you can't control who looks but a friends request??? I had to show my husband to prove I wasn't seeing things! He was furious I mean really angry as he knew exactly what happened and couldn't believe her nerve.
Please help me understand what the hell she is thinking because to be honest I'm baffled!
