How big of a ass does this make me?

On Sunday i was with this girl, who just recently went on a BREAK with her boyfriend. I only hung out with her once because i just moved to this place, so were not really that close. Shes kind of sad, so she thinks drinking will make it better. whatever. We start drinking and i don’t drink that much anymore so i take some sips from my Gatorade and a splash of vodka. Fast Forward…..she gets ”drunk” and we end up having sex without protection….pull out method. GREAT. The next day she flips out at me, after i try to calm her down about how shes probably not pregnant. Now i don’t want to be a complete teenager but, i have done the pull out method a couple of times and it has yet to fail me. I try to calm her down, but than she starts flipping out more because i “took advantage of her”. Notice how i put drunk in quotes earlier. I’ve been around drunk people, i know how most of them act, I’m 99% sure she was not drunk. Also she blames me for her “boyfriend” being sad and how they are falling apart. AKA she blames me for her shitty decision making….you know hanging out with another guy drinking on a sunday night while we have open conversations about how we both want to have sex (before the alcohol)

Let me get this straight, i try to focus more on how this girl is not pregnant and that even if she might be we need to do something about it, and she flips on me for TAKING ADVANTAGE OF HER, and her DEPRESSED BOYFRIEND…..should i be less concerned about the fact that at 17 i might be a dad?
