whatis oh puhlease - you're using 'you can't help who you fall for' really? You MAY not be able to help feelings you CAN help actions - he has HISTORY with his WIFE not you. And yes you fucked him knowing he was married so you ARE a threat to his marriage if his wife finds out.
Lots of married men on dating sites you know that unless you're a complete naïf!!
Seriously get a clue and morals
I'd agree you're equal - equally selfish
Written before I read:
"He wanted me and I wanted him, simple."
Gentlemanly? No a gentleman doesn't cheat! Or buy women!
"Erm. He paid for you to go on holiday with him after meeting you on a dating site. Of course he showed you his expectations. What the hell did you think, that he worked for the Make A Wish foundation?" He knew you'd feel obligated to him, not 'letting' you pay for anything in money meant he knew you'd pay him in kind - which you did
And I can assure you if you were as wonderful as you reckon - he wouldn't be staying with his wife, and wouldn't have tried it on with you in the first place.
