Basically, long story, short.
My best friend broke up with her on again off again bf,maybe a week ago. Me and her ex work together so on the day they broke up I went to ask what happened and we ended up making out at work.
Since then we've slept together 3-4 times, this is nothing like me to do this kinda thing, but today my friend told me she wants to get back with him and asked me to help her. I feel really bad as I knew that she would want to get back with him but I don't know what to do, if I should tell her we've been sleeping together or if I should help etc.
Any advice would be good.
