So I tried online dating. Got talking to a lady who lived about half an hours drive away. We chatted for a while and decided to meet up.
We first met a couple of weeks ago for a coffee and we got on really well so I asked her on a second date. Second date came round and again a nice time was had. We had our 3rd date tonight she came back to mine and we slept together. I asked her to stay the night and she said she couldn't as she had work tomorrow.
I've just received a text from her saying the real reason she couldn't stay is because she is married.
I feel shell shocked right now. She's asked me to be her 'bit on the side' I feel awful about it all. I feel guilty even though I didn't know she was married. I've said I can't carry on but shes being very persistent. How can I resolve this?
