I have recently started having a sexual relationship with one of my Colleagues/Friends at work. We were fooling around for a while and then she asked me to have sex with her, seeing that she was a virgin and i didn't wanna get in that deep. (e t pun) We then had sex a couple of times and i recently told her that it was not a healthy relationship as we were only having casual sex. She is now very upset about this and says i only used her.

I do not want to lose her friendship and have even considered going back to shaging her as this would patch things up in the interim, but then the long-term effects of that comes haunting me again. What would you do, not from an outsider's point of view, but if you were in my shoes..
