Why don't you have a grown up and mature conversation with him about what's going on and that you realize that YOU have been crossing platonic friendship boundaries with him by cuddling which YOU will put a stop to if he's not interested in being your exclusive boyfriend. Is that what you want, to be his exclusive boyfriend? Does he even take you out or do you just hang and play tease to one another?
Stop being so ambiguous by letting boys that haven't committed to anything with you cuddle you in your bed. All that shit does is cause confusion and fvck buddies.
If you want to be a fvck buddy then why didn't you just carry on with doing what you expect him to do? If you don't want to be a fvck buddy then stop cuddling and ask him what is going on.
How old are you?
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
