you're going to burn in hell?
thats not true.
you cant help who you fall for and you cant help who you love.
im only 15 but i know about these things trust me.
i doubt she does.
she probably just thinks nothing of it.
but for now i wouldnt say anything.
just save whatever you have to say to him. untill you can say it to his face.
then she has nothing to suspect.
hopefully you'll realise what you are doing is wrong.
and come clean about it.
because you may be feeling bad about it or you may not but whoever his wife is shes going to be devastated so maybe you should just tell the truth and see what happens from there
but hopefully things will turn out good.
and no you wont burn in hell, he dosnt know what hes talking about [:
good luck with this anyway.
