If somebody that supposedly loved me lied to me about something so important, you’re darn right I’d divorce him.
Like I said though, if you’re okay with it, it’s your life and your marriage so nobody can tell you what to do.
Got married in 1980. Been married to him for d@mm near 31 years. I do NOT break vows given before God and man. My word is my bond, tho it may be to my detriment....
FYI
My mother and her sister both got it... both had kids after 30...Auntie died a horrible death from it... Mom lived till almost 80 and beat it ...
YMMV
