a sex wreck after 33 years of marriage.

my ex partner gave me a std after a night with a common prostitute. This is after i supported him financially for 12 years.
He has told me he frequents the red light area and i have reason to believe he is on hard drugs now. All at the tender age of 60. Likes to pop pills especially speed variety.
I have no alternative but to move on with my son and daughter 19 years and 23 years a piece. It is all so sad.
He is a totally different person to the one i knew for 33 years.

You have my sympathy, but I think you are wise to move on.
