I ghosted someone and now I regret it

I (27) met a woman on a dating app. We’ve chatted for a few weeks. I’ve really enjoyed them. We had a lot of common interests. We were always laughing. Then she suggested we meet in person in a park. We met, we had a while. Then I get a text from an unknown number. She’s pregnant. And she was 15. She said she was 21. I’ve never been in this situation before. I didn’t respond. I just ghosted her.<br><br><br>Now I feel guilty. But also angry. I don’t know what to do.
