Your Thoughts Please

A few weeks ago I was out of town for a business for the company I work for.
During the meeting I met an attractive older lady from another out of town office. When the meeting was over that day I asked if she’d like to have dinner together which she accepted.
We had a nice dinner then went to the hotel lounge for an after dinner drink. They had a band playing so we ended up having several drinks .
Later I walked her to her room. When she opened the door I followed her in so she immediately reminded me she was married.
We chatted for a few minutes then I leaned over kissing her on the cheek. The next thing I knew we were on the bed kissing very passionately.
As we were kissing I started to run my hand up her skirt and she grabbed it telling me she couldn’t do anything because she wasn’t on birth control. I started another passionate kiss she let go and I was able to start foreplay.
She didn’t say anything else until I started to get my penis out then she said no that we needed to stop but I quickly moved between her legs and penetrating her. She yelled oh my god don’t you have a condom? That was the last thing she said until she said ohh no as I came in her.and she had an orgasm.
We chatted for a while agreeing it had been enjoyable for both Ug us then I left.
I didn’t see her again because I had an early flight home.
Yesterday she called telling me she was pregnant asking me to pay for her to have an abortion. She informed me her husband had a vasectomy so she couldn’t let him know.
I’m not sure I’m obligated to take care of it since she knew she was taking that chance.
