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.

So I had my ex round this weekend. It was beautiful. All weekend I kept asking her to take me back. She said some bullshit about needing to think. Fuck's sake, we've been on and off again for about two months, she's had enough time to think. I asked her again before she went. Apparently I'm a bastard for upsetting her. Lolwut?
And the fact that it breaks my heart when we're aart, and that because we're not going out she can just jump on any cock she wants is totally fine. Fuck that. Well I told her I'm sick of being messed about and that's the end of it. Apparently "Things aren't that simle, it's not always black or white". What the fuck ever, it is to me. Either you're my girl or you're not. I guess she isn't.
God I hate women sometimes.
