Ok, I'm not easy to live with at the moment, I quite agree.
I wouldn't, hand on heart, have a problem with porn if it was something we did together. Pre most recent baby, we often used adult books together, no problems, and when I was single I often looked at it myself. (I've been too knackered the last pregnancy and since, I'm unhappy and don't have much sex drive.)
What I've said in the past when we've discussed it is that I wouldn't feel happy looking at other women with him, because I would feel that he was aroused by them not me, and I would feel inadequate. My problem, completely, not his.
What he has said when we had these (what I thought were) frank open discussions, was that he hasn't ever used the internet to look at porn, because it doesn't do it for him. He said this all along through our relationship. Since way before we ever talked more openly.
Now he tells me that he's always looked at porn on the internet, totally admits he lied to me, doesn't know why. He says it doesn't give him a kick, or arouse him.... can give me no reason why he does it (even now, confronted with plain as day evidence - not that it's a crime, I mean the facts that's all - still not being honest about it).
This happens every time something crops up where he's told me one thing, then it becomes blatantly obvious it's not the case. He swings from being sorry one minute he upset me, then he wasn't doing anything anyway, denies whatever he admitted a minute ago, then claims there's nothing wrong in what he's doing, then says he can't believe he did it....etc etc
Always the same, every time.
Just because I'm difficult and insecure (now, it was not a problem for us until it first became very clear he'd lied about his sis-in-law, and he agrees about this) - does that mean it's ok to lie to me? What's the next lie, that's my question?
He doesn't mean to hurt me, I know he loves me and doesn't want anyone else (to be married to).... but why be a lying bastard then? I just feel he will do whatever he wants to so long as he doesn't think I'll find out - not maliciously, I believe he genuinely doesn't want to hurt me -I think he believes his own lies.
