AITA for wanting to cut off a guy who only talks about sex?

This guy and I matched on Hinge, both saying we are looking for something serious/intentional dating. He told me that he wants a relationship but is into cuckold stuff also. I told him that I like his energy/personality but let’s just hold off on anything sexual until this even progresses into anything romantic before going that direction. He agreed but then continues to talk sexually with me. Sometimes I did engage in it but I also didn’t try to make it the main topic of all our convos so I usually would change the topic and talk about any and everything else. (Keep in mind this was all through the Hinge app for weeks). He told me that a family member of his passed away — I would say maybe a week ago or some change — so conversation has been a little bit more inconsistent which is also 100% understandable giving that he is grieving. I simply extended my condolences and a listening ear if needed to talk. The few times he has reached out to me since has been sexual once again and now I’m starting to get annoyed. I asked him for his phone number so we can finally get off the dating app — but didn’t answer the question and continued to talk sexual to me. I told him that I don’t want to continue because it sounds like you’re after one thing and inconsiderate of boundaries, plus ignoring my question of wanting his phone number. I partially feel bad since he is grieving but also, 90% of convos have been sexually, after expressing he wants something serious (but says he is a very sexual person). AITA for doing that during his grieving state? Or did I make the right decision because now I’m getting he’s a weirdo and a potential sex addict?
