My GF and I have been dating for about 4 months now and we're both quite serious hoping this relation ends in marriage. We had been having unprotected sex for a while, until about two weeks ago when my GF asked me to start using protection since some of her friends were getting pregnant and got her shook. 

She had gotten pregnant once in high school (where the guy's parents paid for the abortion) and so I understood that she did not want to go through that shit again so I agreed. We went to the drug store together and she suggested we got the really thin one so it'll still be good. (They are suuuper expensive for a uni kid living alone in a foreign country, like $10 for a box of 5). Anyway. We got back and started getting at it. It was my first time in a while using a condom and so I may not have been the best at putting it on but after some fumbling about I managed to put it on and we went at it. 

Skipping the fine details of the sex, the condom was broken when I pulled out I had already finished believing the condom was an almighty balloon. I freaked out A LOT and it got super awkward really fast. It was about 2 days after her period so the chance of getting pregnant wasn't astronomically high, however the possibility was still very much there. 

We talked about what we should do and I strongly suggested that she got the day after pill as even if the chance was not that high it's much better than having to go through an abortion. A day after the sex she told me that she wasn't in a great mood because she was tired from going to the Gynecologist which I simply had assumed the visit was for the day after pill (we live in Japan and you need to have it prescribed). 

She messaged me today saying that she isn't feeling well since 3 days ago which match up to her ovulation and we're freaking the fuck out that she maybe pregnant.  Turns out she hadn't taken the pill.  Going to the main point of this if she is pregnant, I'm not massively keen on paying for the abortion, like I've mentioned before I'm a broke Uni student and my GF is living with her parents and is decently well-off. I will be fine paying a portion of the costs of course, but I feel like she should have taken the pill and it's not exactly my fault for the condom breaking. Maybe I'm just freaking out early and it isn't actually a pregnancy.

idk... 

am I the asshole??
