I am a man. Is it really counterproductive to care too much about a person?

If you care about someone, it will make you not in the mood to work, which will affect your normal life and backfire; If you care too much and make her feel restricted, not free, or nagging too much, after all, sometimes people need to be quiet, and another person always bothers himself, which will naturally be offensive and counterproductive. If you care and love, the other person can understand, don't reject it, and it won't make you so lovesick that you are not in the mood to do other things. This is not counterproductive, so it is possible, but not necessarily.
