Will my new man leave his boring wife and deadbeat family life for hot love with me?

I'm a 21yr old girl. I'm blond, curvy, with a great heaving chest...I'm UK 32G!! And real! The thing is i babysit for the man next door. They have 2 kids 13 months and 3yr old. I'm new to the hood. Basically him and i have been going at it like crazy this past 4 months. I didnt make the move on him, he kissed me first one night. Granted i used to go round there in revealing tops and his eyes were out on stalks. His wifes not got a great figure, her are saggy and shes big. He is 35 and gorge. His fav way to do it is him at me from behind and that is also my fav so we are really really compatible...and he says he is really hot for me...we meet 3 times per week..sometimes in his car. My mom says its his issue, hes married. She doesnt discourage it. She says hes obvoulsy fed up of nappy land and fancies me like mad. Will he leave her for me? The fact we like 'it' the same way...does that make a difference? He says his wife would never agree to it that way and he gets so much enjoyment from me...isnt that a complemnet? Lots of times when we meet he gives me presents after lovemaking like cute little panties and tells me to wear them next time....wot you think?
