Weiss wasn't dependent on hugs.
Weiss didn't look forward to all of the hugs Ruby gave her whenever they went their separate ways. She simply appreciated Ruby's hugs.
Weiss certainly wouldn't pretend to be upset just so Ruby would hug her to make her feel better. That would be deceitful.
Weiss definitely didn't spend her free time thinking of new ways to get hugs from Ruby. Weiss hadn't bought cookies for Ruby just because she wanted a hug, but because she wanted to do something nice for Ruby for once.
Weiss wasn't dependent on hugs, because that would be ridiculous.
