<human>: Can you condense the text into a few key points?

Normally, I'd say that it doesn't make any sense to continue this relationship but she truly loves me with everything she has and would do everything for me. I also love her and even think about having a family with her.

She was very hurt by a failed 12 year marriage where she was cheated on while he also didn't want to have sex with her.

However, I - subconciously - avoid physical contact as much as possible. I just don't find her attractive, she isn't my type. 

Additionally, I'm not very social or emotional (picture: IT geek) and I don't require physical contact as much as she does. I never had a real girlfriend or felt loved by another person. I'm a total emotional cripple. I can actively bring myself to perform physical acts of love but this - being a conscious act - just isn't enough for her.

I don't want to leave her but we argue at least twice a week and she is very emotional - she is a **high sensitive person** (check Wikipedia). She cries all the time, shouts and is extremely aggressive since she fears that I'm going to leave her. She tries to use guilt as a mean to hold me, to force me to give her what she wants. These fights hurt me very much. They hurt me so much that I get physically ill.

Last night we argued until 1 AM and she said, that I'm her last chance for a relationship and she invested so much, since she is already 30.

I can feel that she is deeply hurt by her previous marriage but I can't give her what she needs. I don't want to hurt her anymore. I want to give her the physical love she needs, but can't.
<bot>: I'm not physically attracted to my girlfriend but love her and want to be with her. However she wants that I love her physically which is exhausting for me. What to do?
