I live with my BF. He has been distant lately, but when I try to make conversation he turns it into an "I'm very busy with work and overwhelmed with my duties...And me having to answer to you is frustrating ..."

I seldom ever bother just to bother, I housekeep as best as possible, but I seem to get under his skin without trying. I know of his obsession with porn, and its taboo when I try to bring it up. In the past, he's told me that it’s a 'God given thing' and that he can and will watch and enjoy without a care on how it affects anyone; "I'm not hurting anyone by doing so.”
Please let me know your thoughts. Am I making a mountain out of a molehill? Please advise

How long have you lived together and what else is going on in your lives? Any kids? Do you work? How long has this lack of communication been going on?
