Depends on situation and person.
If my girl does not returns back on time or she messed up with some guys on subway and I interfere,then it’s good.Possessiveness is good as being protective.
But possessiveness is toxic if prohibitive.
If I dictate whom she can talk and whom she can not,it’s bad.If I dictate length of her clothes,then bad.If I dictate her life,extremely bad. Love is freedom and not boundation.
Love is trust that she will not cheat and not rules and regulations for her. I never like my bird to be caged and love only me. She can stay only if she wants and not because I morally blackmailed her to stay.
