I'm sorry, I didn't realise I'd said anywhere that he'd cheated previously. He actually hasn't been in a "proper" relationship so I might have worded a previous post incorrectly, my apologise.
AF, you make complete sense. I don't believe that fulfilling sex alone is enough. And I appreciate my post may have come across that way. The difference, I believe, is that I have traits which he is attracted to. He appreciates my mind, my work ethics, my love and affection for those with whom I am close, my maternal instinct, etc. I never quite understood when people have said "besotted" before, but this is the feeling I get with the way he feels for me. I think previously, he's been a young boy just playing the field and therefore, he's just chased physical attraction. He told me a few months ago that I am all he's ever wished for in a life partner and would feel blessed if I am the mother of his children. So in terms of wondering what is different about me to the others, I believe it's due to him reaching a point in his life whereby he wants to settle down and he's taken the time to get to know me, the real me, and not just my exterior. He tells me that he loves and adores me often and I believe him.
I'm sorry if my previous posts came across as me providing what he needs to not cheat. That was not my intention. Although he loves sex, if ever it is turned down between us, it's by him because he wants to "hold" me. He tells me that intimacy is not just about sex between us, it's holding me, stroking my hair etc. and sometimes, that's all the pleasure he needs.
