When the both of you sleep next to each other regularly and snuggle up, but nothing ever happens beyond that, he doesn’t want more, he likes you as a friend.
A guy who persists in sleeping next to and snuggling up to a girl that he is interested in romantically has an intention.
Repeatedly putting himself in this position without doing anything beyond this act, is equivalent to a guy who is torturing himself.
It is too overbearing to be this physically close to someone he wants to have sex with and only relegate himself to snuggling with them, each and every time.
There is a higher likelihood he likes you when he doesn’t encourage this, leaving you to be the one to ask to snuggle.
