I think it was part of a short series of dramas, possibly made by the BBC, for valentine's day- stories about relationships.
The one I'm thinking of was a story about a young woman at uni who went on a blind date with her friend's brother who is lovely but she accuses him of raping her. The story was played out in flashbacks to the night of the date. It was really good.
There was another in the series about a guy who starts dating a prostitute who through a series of events becomes one himself.
Anyone remember the series and what they were called? Would love to find them.
