<human>: Can you summarize the given text in a few sentences?

So, here's the story. I hooked up with this girl around 4 months ago. Nothing really serious. We were using only condoms and at some point she started to taking pills for birth control. Two months later, one night we had drunk sex and I didn't use a condom.
Two weeks ago, I stopped to talk to her.
Today she said she's pregnant with a child; went to the doctor and had an ultrasound done. She said that the heart is developed.
She doesn't want a abortion and wants me out of her life. She said I couldn't support them financially, affectively and that I didn't want the baby anyways.
The thing is...she's right. I'm a student that doesn't love her or want a child. 
She's moving to another city soon. And, for context, she already has another son.
My question, that keeps me up at night, is:
Do I have to respect her will? The only thing I could do is bring more troubles.
<bot>: girl and I hooked up, she got pregnant, doesn't want me around and I don't know if I have to be okay with it.
