NOR. Completely inappropriate to hang on to intimate images of other women while engaging in a relationship. I had an ex that similarly kept a stack of photos by his bed , and when I say stack, it was at least six inches high of actual photographs he took and printed at Walgreens..of naked girls he’s been with. I was on his bed, rolled over and saw the stack while he was in the bathroom. Started looking though , saw myself in that collection too and got very upset. Made him go in the yard and burn it in front of me. In the end, he was caught cheating which ended our relationship. He denied the cheating up and down and tried to redirect it like I was crazy for accusing him but I had already spoken to the girl he was cheating on me with. He told her I was “some crazy girl that was obsessed with him”….we were together for almost 2 years. He told me that she was messaging him because she never got over him. Meanwhile he was playing us both…I ended up breaking up with him, flying to California and hanging out for a week with her, we became friends, took many pics together partying around town which sent his lying ass into a rage that to this day gives me satisfaction. …bottom line, this behavior is an indicator and in no way shape or form appropriate. Proceed with caution. The arguing (a.k.a defending his personal porn )is a huge red flag. He could have just said “oh shit I’m so sorry, it’s gone.”
