I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
I am not happy.
This hero is too damaged. His problems too severe. I cannot enjoy a love story with someone who suffers so strongly from PTSD.
I don't find it realistic or advisable that the person who is supposed to "heal" you, has sex with you.
Relationships (and especially romantic ones) are full of landmines. Not good for someone so deep under.
What I would like to say:
Please, dear authors, refrain from giving your heros all those awful mental problems, those debilitating sufferings. In real life this is not attractive and not wonderful. And this alone does not make an interesting person - just a sad one.
And SEX DOES NOT HAVE HEALING POWERS.
