I don’t send him nudes or dirty talk just casual convos

I’ve been talking to this older man he lives in PA i’ve been talking to him for four years now. I have seen him in person but public areas like bars and I never went home with him but he would pay for clothes I wanted or an outfit for me to wear when we hang out at the bars. I was talking to him since before I got in my three-year relationship I have now with my boyfriend. And he’s very respectful of that and he doesn’t ask me inappropriate stuff or anything like that now. I told my boyfriend at first my boyfriend how to think how he felt about it. He read our conversations he knows that the older man buys me clothes and all he wants is a picture of me wearing the clothes in return.. but now I moved in with my boyfriend and The older man I’m talking to wants to buy my Halloween costume. ( i’m going to Vegas with my boyfriend for Halloween) my boyfriend is okay with that but I don’t think if I would be okay if he knows my boyfriends address. Which he has known my pass address before from sending me stuff. Or am I thinking too much about giving him the address?
