This very christian girl and I have been talking for awhile. We're now dating, and have been dating for the past couple of weeks. We've never really connected like two people should in a relationship. Things are just awkward, without being awkward. I can't reach her on an emotional level.
Anyways, cutting to the point, she got turned on, I got turned on, and we had sex. I made sure she was the one to put it inside of her, not me. I checked on her the entire time, asking if she was okay, and asking if she was comfortable. About halfway through she looked really uncomfortable and I stopped and asked her, "Do you want to stop?" and she said "no." I said, "[name], don't lie to me, we can stop and that's completely okay." and she said yeah, lets stop.
I had parked far down the road so her parents wouldn't see my car if they happened to get home before I left. So she walked me all the way to my car and I kept asking her if she was okay and she kept saying she was fine. I offered to take her home several times and she kept saying no, that she'd rather walk and she got mad when I insisted on taking her home (it was late at night).
She completely shut down to me and regrets having sex with me. I feel like I took something valuable from her that can't be returned, and time can't be reversed. What do I do? How do I act? Should I feel bad?
TL;DR I take girl's virginity, she shuts down and immediately regrets it and I feel like I took her life away.
