<human>: Can you give me the gist of the text in a nutshell?

I've known this girl for about 3 years, we went to primary school together. We weren't good friends, but we hung out sometimes. I walked her home from school one day about 6 weeks ago. On the walk we got talking about sex and kissing and stuff. When we got to her house she kissed me lightly on the lips. Then she asked me if I wanted some food inside , she said her parents were out, but they wouldn't mind. So I said yes.

When we were inside, she was very close to me and she took my tie off. When we were watching TV she kept touching my leg. I thought I was going crazy, I thought why would she want to have sex with me? Eventually we started kissing and it led to us having sex. It was my first time, I'm not really sure about her. 

Everything was normal until about a week ago when she skyped me and told me that she took a test and she was pregnant. Her mum is saying that she should keep it. She said that abortion is a sin. We go to Catholic school, but I don't really believe in god. My friend said that she didn't want it at first. But her mum convinced her that it's a good idea. I haven't told my parents, but they can't do anything. 

I know it was stupid but a beautiful girl wanted to have sex with me. What was I supposed to do? And I didn't have any condoms. Obviously I should have said no, but it's too late now. What do I do? I can't have a baby.
