Don't know about unhappy with her or the relationship, but your insecurity (and desperation to some extent) does come across petty strongly.

Why else would you keep asking for a rating repeatedly. Some people might like that vulnerability in their partner because it gives them a false sense of self-worth, but some might get turned off by it because they are looking for a strong partner who'd provide them with security instead of them having to provide it. If you getting a stable job bumped up your score in her mind (obviously I don't know if that's the case for sure) then chances are she is looking at you to provide that security.

Unfortunately, contrary to fairy tales, insecurity in either partner can't make a happy successful relationship. Your insecurity is your responsibility and hers is hers. Work on yourself and your SO will change (either she'll change as a person or it will be another person - if you know what I mean).

Good luck to you both.
