I'm jealous of my ex's new girlfriend. Not because she's with him, but because the b***h stole my family stare It's just weird seeing her and her child with my "in-laws" still. Other than that I'm not jealous of anyone/thing.
That seems like a really normal and natural thing to be jealous about. I mean, you're not jealous because someone has nicer shoes than you, you're basically grieving the loss of people that you really cared about.
That's what a friend of mine told me too, which makes me feel better about it.
