<human>: Provide a brief overview of the text.

We have been dating about 3 1/2 years now.  

We've been happy overall throughout the relationship, but she has recently been diagnosed of vertigo accompanied with a screaming tinnitus.

 I was unhappy with this relationship even before all this since I was starting to realize that I see her more like a best friend rather than a SO. I have been through a number of relationships but not anything like this because due of her vertigo and tinnitus, she became unable to sleep by herself since she gets worried and depressed(which makes both symptoms worse). 

We have tried sleeping pills, going to the doctor, and melatonin but nothing works to help her sleep because it seems like the anxiety of having those symptoms for life depresses her so much that she can't fall asleep. On top of that, she has a very aggressive and abusive set of parents that physically harm her.

So I've been letting her sleep in my place for a few months now, out of the respect I have for the past good times we've had with each other. She's very grateful and still madly in love with me, but it's even worse for me to live with her since I can't look at her the same way as days progress. 

I can't look at her the same way and it kills me everytime she tells me she loves me or how much I mean to her (she said I saved her life and etc.). I am her first boyfriend and first everything, while I've had about 6 different relationships before (2 being long term, and 3 including this one).

To keep it short, I want her to move out and be happy without me, but that seems like it is unlikely since those symptoms can last for life. I also want myself to be happy by getting out of a relationship that I do not want to be in. However it seems like this is impossible until she figures out a way to sleep by herself which is hard because she does not want to go back to her place and I do not feel safe to let her anyways, yet she has barely any friends close enough to let her sleep over for that long duration until she "habituates" to her symptoms.
<bot>: Gf has medical problems and abusive parents so she moved into my place. I've been wanting to break up but missed my timing.
