So I am in shock these last days. I found out that my bf werith whome I live watches people in building across with binocular. I find this very disturbing and don't know what to think or do.

We live together for two years and we recently moved to a new apartmant. The building across is very near and you can see into apartments at night. At first he made comments about the couple from across. At first I thought it was just curiosity because he never had neighbours so close. He didn't hide that he was interested to check out what they do. Than one day I found binoculars by the window. I was shocked that he would invade someone's privacy like that. It is very creepy. They stayed by that window for days so I took it and moved it and he got pissed. I realised he was using it a lot. SHOCK.
So, I confronted him and he says it was just curiosity, that I can not control what he does....
I guess his method is to give any answer and waiit until I get over it.

We had similar talk about his porn before but I gave up because he either says that he knows it is bad and that he will cut it down but he never does (can't). Or he says I can't expect him not to watch it because he does it his whole life and it does not concern me.

But this new discovery is really disturbing. He today said that he saw one girl naked across the street and he was checking if it will happen again.
I am not sure if it is sexual, does he really want to see nudity or it turns him on he can watch people without them knowing.
What is this ? How worried should I be?
Is this something that is deeper issue?
I appreciate any insight.
