Almost all people fantasise as a way of escaping the boredom or routine or predictability in life. And unhappiness, stress, fear.
for men that can go involve porn in a lot of cases. Not in all
for many women, we may not all use porn but we can still construct elaborate fantasies that offer that excitement in our head. Even in their most mundane form we all, men and women have day dreams about our perfect partner, perfect house, perfect job, being a superstar, winning a million pounds etc . Most of us would be hideously embarrassed if someone else demanded access to that inner workings of our mind and imagination. These thoughts are private unless you feel safe and secure in sharing them with someone else.
while many women, including me, are horrified about what porn does to women and how porn shapes society and men in such an awful way, it is another manifestation of this fantasying.
No one, not even your partner wants that exposed to someone they do not trust to be supportive. Of course you are not supportive, I wouldn’t be, but that is why he is angry. You have in effect shamed him and intruded into a very private place in his mind. Don’t delude yourself this has started as you are pregnant..he will have always done it but probably got a bit more frequent or careless more recently. It isn’t unreasonable that he can have some confusing thoughts about having sex with you while you are pregnant- that isn’t that unusual.
sometimes it is way better not to know what goes on in other peoples heads. It is a completely naïve statement to say there should be no secrets between a couple- everyone needs a place they can escape to in their heads. Allowing each other to have mental space and private thoughts is necessary.
I too was upset when I first realised my ex used porn. I was never happy about it, certainly would not join in, could be regarded as a prude about it. But I eventually realised that you have to give head space to each other. Right now you’re shocked and angry. Please don’t do anything rash . Try to remember this isn’t about you, it is about him. It is about how he fantasises to find a space in his head away from the hassle, frustration etc of life
if you object to content he is watching, then don’t make it about you. Wait till you are not as emotional and discuss it with him form the point of view of does he think these women he watches have free will to do what they do..and does it sit right that he is part of that abusive culture.
he is, as other said, perfectly entitled to privacy. As are you. Having passwords you don’t tell you partner is normal. Please do try to come to terms with that.
