Are these sentences grammatically correct and natural enough? ▪ I have a different take on things from those who believe feelings of possessiveness with loved ones to be toxic and controlling. To such people, let me pose this question: Could you ever feel possessive over someone you didn't love, like a total stranger? The answer is a big fat no. We only feel possessive over the ones we love—the ones we care about the most and from whom we expect the same treatment. So, our possessive feelings result naturally from the attachments, expectations, and care we experience with our loved ones, and there's nothing wrong with that.
