GGG My xh's issues were different - and more resolvable, paradoxically!!

You might find it helpful to talk to someone who specialises in dealing with marriages where the partner is addicted to pornography. Understanding the sources of this, and how to manage your response might be helpful - just a thought. With the easy availability of pornography via the internet it is a growing problem.

More seriously your husband probably needs to be careful. It is very easy to start downloading stuff which is illegal, without quite knowing how it got to that.

My understanding of pornography is that it can escalate . . . . sorry if I have strayed into painful territory, but I know people who have had some experience of this. The internet seems anonymous, and that is one of the problems. But it isn't, it can be very traceable.
