Advice needed

So I'm talking to my ex again and we had this intense conversation and he was saying how he wants to have an open relationship with me. During this conversation he told me that he's been getting naked pictures from some random girl he then said that he sees nothing wrong with getting naked pictures he said it's a guy thing. I feel like it wrong I got really upset because I asked if we're dating and you get a picture are you going to tell me or are you going to keep it to yourself he didn't give me a straight answer so I hung up and he hasn't called or texted since my friend told me to wait 3 days before giving up. Am I being over dramatic or do I have the right to be upset
