Am I being selfish!!

I been in a relationship for almost two months with this amazing guy that loves me and my two children, everything is going good but he has GAD (generalized anxiety disorder) I try to surpass that and enjoy my time with him, but sometimes it gets out of hand, he's always asking how I am, what am thinking about,, and if there's a problem where there's not? What should I do? Or advice to deal with it. I am very patient but sometimes it gets overwhelming....
