hi, welcome to pc
i hope you find friendship and support here
in response to your post, i feel so sorry for your having suffered so long with this infidelity and pain.
my frank opinion is that after all this time your husband is not likely to change
and i wish you could consider getting out of the relationship completely and working on healing yourself
i would hope you would find peace and happiness in your life - beyond this loser.
no one deserves to live like that.
many of us have suffered the same or similiar issues in relationships
i'm here if you want to talk
all my best to you hon
