Since you clearly don't have a handle on this I would not reconnect with her. She doesn't need to have an unsupportive person in her life and the negative emotions you feel are not good for you.

If you really had a close friendship you would probably be happy for her that she has met her goals. Close friends support each other even if they sometimes disagree. It would be beneficial to work on this so your jealousy does not spread to other friendships.

I come from a big family. We all have different financial situations, but I have never once been jealous of my siblings who have multiple houses or go on big vacations. I am happy for them that they get to have those experiences. I also don't think I am any less important to them because I might get a couple of overnights at the beach a year.
