We ended up going out on Saturday night, had an awesome time, and I spent the night. Nothing happened until Sunday, late morning. We were both laughing about the night before and cuddling, etc. I went for the kiss and she was into it, so much so that she initiated sex. I am kind of ashamed to say I slept with her after only one "date" but, it was hot and I haven't had chemistry like this with someone in a long time. She gave me butterflies.
I left her apartment, and she texted me shortly after. She didn't really say anything about what had happened, just light-hearted banter. She made a comment about loving to cook and wanting to make me dinner one night, go to a haunted house, etc. Basically a good indicator that she wants to see me again.
After some time, I sent her a message telling her that thinking about our morning gave me butterflies... she responded with "i had a great time." A little vague, but ok. I change the subject and we continue with light-hearted conversation, but she seems.. different. She stopped responding quite abruptly after a while, so I let it be, assuming she would get back to me in the morning as she normally would. Well, today went by and I didn't hear from her, so I sent a text around 5ish. She said "super busy, working a double. how are you?" After that, the replies were a bit short and pretty spaced out, even after she was done working. I know that I don't know her, but I can definitely tell when someone has taken a step back. I texted her "goodnight, text me tomorrow :)" and she said "will do... sleep tight."
What should I do? Should I back off and wait to hear from her? Maybe put the ball in her court? Did my comment about butterflies spook her? She's bisexual and I don't think she's ever dated a girl, she's not out to her friends/family, and I probably freaked her out. I have a huge crush on her but I don't want to fuck it up. Part of me feels like I should back off and play it cool for a while, but the other part of me is like wait, no, I like you, and I want you to know that. Maybe I'm jumping the gun; I wasn't expecting to have such a strong infatuation so quickly.
Any advice would be appreciated!!!
