Simon,
Im not going to put up some advice saying ive got experience..Im very inexperienced when it comes to things like this. Im a female. My ex partner was a detective. the relationship was violent, he cheated on me multiple times, i got an STI from him...and he use to look at porn.....it was something that was a contributing factor that helped destroy me as a WOMAN!! if you get my drift...
it can do damage to a woman....ive had a heap of domestic violence and sexual assault counselling and it IS a form of abuse.....
fakesmile you are completely wrong and out of line to say that his wife is 'not doing her job'
sexual encounters within a relationship must be agreed upon and consentual.....
however - now that i have said this...try not to let the disappointment destroy you over it....treat it like you've gone to the doctor and he has told you you have an illness...after the initial shock and grief.....you move into the stage where you try to manage your illness or get it treated..... im NOT saying this is an illness...just an example....
my only bit of advice is to go and seek some counselling....in regards the relationship.....earning back trust...dealing with your wifes issues that she feels betrayed...you should seek this on your own...and also as couple counselling...this will hopefull show your wife that you are serious about listening to her, acknowledging how you have hurt her, and apologising and how you really want to earn her trust cos you love her BLAH BLAH BLAH....you get my drift.....
and i cant comment on the porn bit bec i know not much about it...just that there are varying degrees of porn....
so im sorry i cant help you in anyother way - but the advice i have given i know is the best bit of advice you can recieve...
