Why do men respect certain women more than wives?

Anonymous
A married man constantly searches for girls to cheat on his wife and wanted me to become his mistress. I liked the idea too, please don’t judge me. When I said I’m innocent, he was surprised and took time to proceed whether I should have my 1st time without normal relationships or not. He said he thinks I’m a good person that’s why he doubted his actions now. Then he texted me “I had a lot of thoughts on that and decided it’s not a good idea for you. I had a lot of relationships and trust me, this one’d not end well for you. I think you’re a very good person and the way of mistress isn’t for you. You disappointed too early in normal relationships. It may seem strange but I respect women too much not to do that to you despite you don’t mind now. My morals won’t let me do that. I hope we still can communicate, I will always help you when needed”.
Please help me understand:
1. Is it real guilt as he can’t give me fulfilling relationships and doesn’t want to use me and throw away like other girls?
2. He decided not to put me through pain and loneliness and said it frankly and let go, but he keeps on lying and cheating on wife without remorse, when I asked him, he said if they divorce someday, it’d not be a tragedy for him.
Does it mean he respects me more than her?
