Annoyed With His Friends

So my SO coworker sent nude pictures of his wife to my SO. Instead of deleting my SO saved them privately to his phone . He told me about it,but I still am disgusted with him 😫 he even had the audacity to be like well you never send me pictures and it’s just like porn .. like wtf? I just had a baby 8 months ago and I am so ugh about my body . How should I feel ? Advice please !!
