Is she even interested in me? Should I ask her?

We went on a first date a few days ago that went really well. We got coffee, went for a walk and made out before going back to my place and chilling for a few hours. We made plans to hang out again a couple days later but in between those days she wasn’t that responsive and didn’t initiate any texts. When I asked if she was still down to hang out yesterday she said yes so I went over to her place and we watched a movie and had sex and I spent the night. She’ll be away for the weekend so I asked if she wanted to hang out on Monday and she said sure. We didn’t really cuddle much though after sex or during the night/morning. The next morning she was nice but not affectionate. I gave her a hug goodbye before driving home. Nether of us have texted since.
