I am sorry to say this but I do not think that he is in love with you nor do I think that you are in love with him. I think you just want his attention and he feels the same way too. Maybe his wife is not giving him enough attention that he likes so he is filling up on you. Oh, your situation is kind of illegal, too. Sorry. It is just not going to work. The Age gap is huge. You will get over it. It is only a matter of time. Thank you for being honest. I wish you all the best.
