Yeah, I think Tony is feeling Carmella withdrawing from him. In the past, Tony has always had his goomahs and has kept things from Carm, but she has always been there for him 100%. I think with this Furio thing going on, Carm has been a little distant from Tony, and he can sense that she's keeping something from him. Svetlana was someone who listened to him, and that probably was something he hadn't experienced in a while.
