I have to disagree with this, at least the "love is not having someone hang all over you" part. People and cats show affection in different ways, and it's important that the wants of both parties are met. It sounds a bit weird to apply the typical love languages concept to cats, but it does work in a way. If Waffles feels love from her cat via physical contact, that's totally fine. Maybe her kitten prefers something else.
What do you do ? I strongly suggest you don't get another cat because you have unrealistic expectations of what a pet can provide you with. I'm not calling you a bad person. You just have some unrealistic expectations that need to be addressed before adding another pet to your household. I don't know what your experience is with children but they are far nastier little beasts in the beginning than any kitten. Love is not having someone hang all over you. It's accepting each other for who we are. Human and animal.
But I agree that another cat may not be the best idea yet. 6 months is young, and time will tell if he's a lap kitty or not. Hang in there!
