@sooooconfused,
why is she telling you she's doing well?
perhaps she thinks of you as a friend and thinks that as a friend you may have been concerned about her
if you are not concerned about her, leave her alone. if your only interest is romantic, leave her alone.
if you're a friend, try to understand that she's letting you know she's doing better. end of story at this time.
I find it odd that you think that jealousy should come into play in this at all. Is it a bad thing that she is doing well - without you in her life?
