Input: I started a new job in a new city. On the first day I met this awkward girl, but very sweet.
I had no place to stay and  I was just starting up in this new place so she offered me to stay in her spare room in her apartment.
I started to realise her perfect relationship with her boyfriend wasn't that strong, not as strong as they made out.
He turned out to be massive addict (you name it and he was on it). 
So this girl is my co worker, and after several lunches and drinks she started to tell me that he's never hit her but has emotionally abused her.
One night she and I were getting drunk and she kissed me. I let it happen.
Since then I have seen a spark in her eyes, she's more chatty and outspoken.
Even though I like this girl I could not accept her as an actual girlfriend, she's too anxious, quiet and awkward.
I find her physically attractive and feel like our kiss has given her the courage to leave her abusive boyfriend. But I feel like she may expect us to be a couple if she breaks up with him.
TLDR: am I the asshole because a girl cheated on her boyfriend with me but I don't want to date her.

potentially breaking up a "strong couple"
