There’s this guy I’ve known for a while and I hit him up about a friends with benefits because I wanted to be done with relationships. But I’m wondering if he likes me or something?

I started to suspect it because he told me he didn’t want me hooking up with anyone else. So I asked him about flirting and he said that part he would just “have to be okay with if it happens”. Also, a mutual friend told me that he’ll either only want to hookup or he’ll keep messaging you. And I do notice that he is starting to talk to me more, but then sometimes he’ll randomly leave me on open. One time when that happened, I didn’t answer because I don’t like double texting and he later on mentioned something about how I don’t talk to him as much as I used to. And one time when I was upset and didn’t talk, he asked if everything was okay and was saying he noticed I seemed off. And asked if it meant that my feelings were changing.
