How Can I Distance myself??

Hey. I have this Friends with benefits situation and im scared because I sometimes think about him or all I want to do is talk and just hang out and be with him all day. What is wrong? Is this normal? Im scared he might leave if I tell him I feel this way. I know communication is good too but still. i mean dont get me wrong idgaf if he does leave then he obviously doesnt matter and appreciate me but idk we act like and even do couple ish things but idk what should I do? I know I am failing but please help!! 😭

Is this feeling all due to the sex ? He has feelings for me too though but just doesn't want to commit in a relationship because it is too exhausting for him rn. But would it be bad if I just feel this way maybe even act on it and not want a relationship either but still kind be in a "relationship" if that makes sense? in short, I dont want a relationship with him, but at the same time I want to do couple things and just have feelings for him still and do want him. So I am confused.

However, What can I do to distance myself if I need to? Especially other than talking to other guys cuz I am doing that but it doesnt help because I still want him... :/.

Is this unhealthy?

Please help. Thanks!
