I thought that their concern for RP's son was the better half of it. If I were to de-translate RP's questions back to the way they were in their original form (the way her relatives said them), I would have to conclude that they are JEALOUS, as opposed to ENVIOUS, of her happiness.
However, I don't know them and I cannot predict when or if they will "come around", or whether things will have to get worse before they can get better.
RP, I apologize for addressing you as the third person throughout the rest of this post. I'm sure you will forgive it just this once.
