So I got some dumb bitch pregnant

I only fucked her a few times to make my ex jealous, she was five years younger than her.
Funny thing is I've been fucking my ex and it looks like we might get back together as she's deciding that she doesn't want any of those other assholes who aren't going to put up with her kinky fantasies.
What the fuck am I gonna do though? I've got some stupid seventeen year old coke whore pregnant. I always wanted kids, but not with some retarded girl who lies to me about her age, where she lives, whether she has a job, and of course, the kicker, she lied about being on the pill.
Why did it have to be her? Of all the girls I've ever known, all the ones I wanted to keep the kid fucking aborted it and this crazy bitch wants to keep it because she knows I'm not an asshole who will run away.
I'm not going back to her, but what the fuck do I say to the ex I'm getting back with/fucking that I love?
Why am I such a retard. How do I get myself in these situations.

Got through to her. The abortion clinic want her to come back a week later, showed her a bunch of leaflets meant to dissuade her from doing it. She says she wants to get it out of the way because she's scared she'll change her mind, but doesn't think she will. I told her (same as last time I spoke to her) that if she wanted anything or wanted me to go to the clinic with her, I would.
This fucking sucks.
