Is it wrong for me to feel relief that my ex downgraded?
You mean he is dating someone with less social status than you?
Yes, I was the only one who had everything and he didn't work.
Well at least he found someone and you should feel happy for him and let go of the past. It seem like you are still unhappy with how the breakup transpired hence you are spying on your ex's love life? You shouldn't get involved or snoop on your ex's love life because that will be detrimental to your mental health.
That's not true. I just want to be with a man who have the same status as me.
It's fine you want to be with who you want to be with. But still you shouldn't judge your ex based on their decisions. There is no reason for you to put in the mental effort of worrying about it.
