Well whenever I hear horror stories of parents constantly voicing their disapproval of their child's relationship, badmouthing about their partners to their child and others, threatening to kick their child out of the house or disowning them, trying to set them up for a date with someone else and going out of their ways to make their dislike super obvious... that makes me think that's the total opposite of love.
Love from any close one (whether it's a partner, parent, friend, etc) should never be controlling, toxic nor overwhelming to the point it makes you argue or hate them. Would you tolerate a friend controlling your life no right? Same thing. Are those really the actions of any loving parent?
