Met this woman while walking, started talking to her, traffic light after traffic light. Eventually I asked her to give me her email address. She took out a pen and paper and wrote it for me. I asked her if she was busy, and she said yes she is on her way to somewhere. I teased her in the end and said, "I was going to invite you for coffee". She suddenly replied, "no I have to go to my husband's friend's wedding", I replied "don't worry I'm not trying to hit on you, just wanted to talk for a bit more"

Basically she was very open to conversation and was looking at me intently, and even walking to match my pace. But the moment I asked her to get coffee she brought up her husband. What does it mean?
