Visiting home. friends with benefits offered his place. What does it mean?

I am going home and clearly have many places to stay when I visit, but my 8 year friends with benefits asked me to stay with him for the week. It’s a first time request which struck me as odd. It is also the first time he’s not living with his sibling (who I have a bad relationship with) . I have no idea why he is still entertaining me after all these years. He’s a very handsome, smart, funny and successful gent who can have his pick. Why would he want me around for a whole week? I feel like it’s too long to entertain someone just for sex. But what do I know?
Also I don’t have social media but he always remembers my birthday which is so weird because I literally mentioned it once. Previous friends with benefits have never been that thoughfful. I don’t know these things without an alert. My girl friends say he does these things because he has feelings, but girls always say that. I don’t know if I should take this relationship for what it is (fwb) or if he wants more?
