I have a problem and i really need some advice, please?

I met a person a while back, i met her during some business transactions, she took a liking to me and wanted to really get close to me ( I did not have any feelings for her and did not realise that she had become obsessed with me). She is about 10 years older than me and shes married!!, anyway she use to make all these fake business meetings where i would i have to come meet with her to discuss something "important", little did i know that it was to spend time with me. This continued for a while, i started to become suspicious and thought she was up to something sinister, i then sent her an email making some false allegations(it was unintentional, i thought i knew what was going on), she ended up having a major depression and having to see a psychologist, she then later asked to see me, so we met, and she told me that she was in love with me, i was shocked,
