OK brief background history:
We met 2 years ago and are very happy together. He is a couple of years younger (I'm mid 40's he has just turned 40) than me and has been in 2 long term relationships before me. I have 2 children from a previous relationship. We all get along great.
BUT I know that he would like chidren of his own one day as I asked him a couple of months after we met. I've been sterilised and can't have any more of my own so this isn't an option for us.
I have this little niggling doubt that one day he will resent me for this :(
