That's a shame about your friend, LV... unlike Ann's friend, though, you weren't running out and doing all the things she had told you she'd like to do someday, over and over again, neglecting promises made to her, and bragging about it all to her.
You were sharing some good news with a good friend, who should have been happy for you even if it did secretly make her envious. She had what you have now and gave it up. She knows that, but instead of putting the blame where it belongs (herself and her first husband), she's dumping it on you because you have what she wants.
When you catch crabs and put them in a bucket, they don't usually escape. This is because when one crab gets to the top, the other crabs will pull him down.
Maybe she'll think about it and realize she's wrong to blame you for her bad decisions. But you have nothing to feel bad about... you weren't being insensitive or rubbing your friend's nose in it.
Congratulations on your new job! You have worked for it and earned it. Be wise with your money in this crazy economy, but enjoy your new non-paycheck-to-paycheck life.
