I shudder at what I haven't found out on my own
you will never find out everything. in fact, you can stop your investigation right now. your husband is a drug addict. and he can and will do anything and everything necessary to keep using. and then do whatever it is he does while high. he is involved in a second dark seedy lifestyle with dark seedy folk doing dark seedy things.
and what he is doing is a violation of what being married implies. that he admits to using ESCORTS for any reason does not make him an honest person. he's seeing what you will allow, what he can get away with.
you can't change him, but you can certainly re-assess what you want your own life to look like and to be about. having a tracker on the old man's phone with barrier signals to alert you when he's being a bad boy.....maybe we do that for our teenage children, but should we be doing that for the supposed ADULT we married? just asking..........
