Married friend sends dick pics?

He sounds like a scumbag. If you're not responding to him then you aren't contributing to it, so it's not your fault at all. If he's a cheater then he's going to cheat, whether it's with you or with someone else. I personally would not want to continue to be associated with someone like that and I would distance myself from him. I have no respect or tolerance for cheaters. He's not only disrespecting his wife but like you said, it's disrespectful to you also, especially what you said about him touching you inappropriately when you hug. I would recommend getting out of that situation and just distancing yourself if his behavior makes you uncomfortable. If you've already told him you don't like his behavior towards you but he still acts that way then I doubt he will stop.
Show his wife, if you are friends and she ever finds out the friendship is over.
