Deep depression

My ex-ex boyfriend adopted a son and soon he'll become a father of a little girl. My life is a disaster, I'm happy for him but it's weird that after our break he could grow up so quick - when we were together he seemed to be the most easy-minded and lazy person in the world. I feel a bit of jealous and envy for his happiness. I hope, the girl which he had found, loves him a lot and she will make him happy.
Is that normal that I feel like broken to pieces?

    Remove the "of"  and leave:  "I feel a bit jealous"

     Write:  "I feel a bit  jealous and envious of his happiness.

I hope the girl he found, etc.

    Write:   "Is it normal that I feel...etc."
