Cyberdating again

I had another instant message chat with the man but I can't see anything good coming from a relationship with him.

It was a brief chat. He seems very keen on a relationship and flattered me with comments about how attractive I am but this type of compliment has always embarrassed me.

Anyway, my interest in him started to wane from the moment he told me his marital status. I don't want to be his bit of fluff on the side.
