Recently, my friends with benefits has changed his behavior?

We are both mid 30s- and we've been friends w/benefits for 3.5 months. Mutually agreed upon, we both get along great as friends and have so much fun. We both agree not looking for something serious.

But lately, he is;

- communicating w/me a lot more

- expressed that he really enjoys me as a person and not just the sex

- inviting me over whether sex happens or not

- wants to see me more

- started cuddling all night when w/me i. e. playing w my hair, head kisses, kissing me outside the bedroom

- telling me stuff like "can't wait to have you in my arms" "can't wait to see you again " << he never was saying stuff like that before.

I am OK being friends with benefits but this behavior is new, is this normal of a friends with benefits
