Feeling like a predator because I (M23) slept with someone (F25)

I (M23) had a thing for a college friend (F25) for the past 4 years , but she had been dating a friend of mine. Few months back she broke up with him, and since college is over I haven't been in contact with him either. So I asked her to meet for a coffee and she agreed . During the coffee meet I mentioned that I am home alone for the weekend as my parents are out on a trip and subtly asked her if she wants to grab a drink and watch a movie at my place at night . She agreed to come over but mentions that she has a new boyfriend who lives in another country. I was surprised but atleast she did agree to come. We had drinks and saw movies . At around 2am she starts trauma sharing with me about her bf , family , friends, etc, and starts crying in my arms ( We both were pretty drunk by this point). Shortly after she leans in for a kiss , we kiss and I pick her up to take her to my room and we did the deed, it was pretty intense and we both came . I woke up with a migraine to us both naked on the bed remembered what had happened . I sat besides her and woke her up , she looked at me grabs my face towards her a kisses me . After taking a shower and having breakfast she booked an uber home. While leaving she says " I enjoyed last night and let's so it again" . I was pretty happy about what had just happened. But soon after she started behaving odd. When I asked her to meet she used to say she is busy and didn't talk about that night much . After few days she just blocked me. And since then I have been feeling guilty that maybe she must be thinking that I took advantage of her or forced myself on her because she was drunk . But I had no intention of hurting her or making it feel forced. It makes me feel horrible thinking someone feels I assaulted them .
