Oh, no, that's not true. One can be jealous of anyone their partner spends time with, enjoys being around, has inside jokes with, co-workers, whatever - doesn't matter if it's totally platonic. I felt jealous about some of my ex's friends. The dynamic doesn't always control that. Jealousy usually rears its head when insecurities or self-doubts are present (and there's always more stuff underneath it).
