Please guide me friendly to face the difficult situation.

thanks ravinskye for yr prompt reply. My pic is not very old, its just 4-5 months old and he is very impressed with my pic, he founds me very hot, i dont know how? and he keeps telling me occasionally that i m very hot, i have told him that i am only 4 years older than him and to that extent he didn't show any objection and said its not much difference and he won't mind but if i tell him the 15, I dont know what heaven is going to fall on me, that much wud definitely be a shock for me and can destroy our relationship. I know I have maintained myself quite well but then the signs of age difference may be I wont be able to hide. He is just 37 and me 54 and I have told him that i m 41, and I know I can give a look of 40s, but still is there something, that he can catch me. Ravi he is in so much of love for me that I just cant dare to tell him anything, we r meeting on monday for half an hour and i just pray to God that sky remains on my head. and that meeting shud not be our last one, I just pray to God. Please give me some suggestions and advice to handle that difficult time. thanks once again,
