<human>: She left me because she felt her recovering from her mental issues was being hindered by our relationship nurturing an unhealthy dependency upon me for her happiness. Everything was perfect between us otherwise. I want to help her but it seems the best thing we could do is give her space and call our relationship off completely.

But I love this girl, honestly. I have had many girlfriends but she is the one. It will take time and I know I need to keep busy, but I honestly think there's a future for us together. 

Am I being too optimistic? Could there be a future for us? How could we reconcile when we can't speak in order for her to be happy in herself? How would I know when that had happened?

I really do not want to let this go and I'm really worried I haven't fought hard enough for our relationship.

Someone please help me out. I am so confused.

Can you provide a brief rundown of the text in within 3 sentences?
