Yeah projection all the way. Ironically I think they might be onto something in a weird self fulling prophecy kind of way. First in that their possessive behavior will lead their kids to date in secret. Second and this might take some time to explain, but I always thought we learned what love is from the people who raised us. Basically Freud in that we marry our parents. A lot of their kids will mimic or be attracted to their parent's abusive behavior in others thinking that is what normal relationships are and end up miserable like their own parents.
