Red flag if they ARE mad. I knew a girl online who I was texting and dating until about a week in when she said she needed me to send her nudes and blocked me when I said no due to sexual trauma.
Whoa, stay safe, kid, like the other commenter said.
Make sure parents are involved. Could be that this person just seemed to be a "match" for you and you became horny after that. About the pregnant thing, wear condoms, use birth control, do anal or other sex acts that don't involve penetration.
Or just do casual dates, and she must be a loser if all she wants is sex from you.
I don't know, you're probably right, but to add more info, she acted very attached, trusted me with a lot, I was like her favorite person, and she even wanted me to move to another country to live with her only to discard me because I wasn't useful to her anymore.
Thanks man!!
