Just got out of a 4 year relationship a month and am trying to swallow the pill. I was seeing my first plate for three weeks when she just went ghost. I realize there's oneitis at play here since I'm butthurt over being ghosted, but still want feedback as to how I could handle this better.

Third girl I ever go out with, it's also the cutest girl I've ever gone out with so my game is on point. Meet on a dating app and we chat about nonsense over wine, I invite her to mine over, and instantly fuck her brains out for hours. Best sex I've ever had. She goes home, texts me it was nice meeting me, I do the same, and forget about it.

She texts me the next day about how sore she is etc., I laugh it off and text her a little here and there. Plan a second date 4 days after the first at a bookstore. We meet up, have fun, then go back to mine and have sex again. Overall, there's very high interest on her part, she can't keep her hands off me as soon as we meet, etc.

She starts texting me comfort tests which I empathize and change the subject with. I think she would text me first everyday with random shit and I would respond playfully/ignore. The third date is dinner at mine a week after the second.

I'm free two nights before our dinner date so I tell her I'm going to pick her up for ice cream once she's off work. I do so, fuck her in my car, then drop her off home.

The next day, she texts me first again, I send her a random text in response, and forget about her since I was out fucking another girl on the first date. At 2am I drunkenly text her the time I expect her over for dinner.

The next day she texts me suddenly saying she has work that night, and that she's sorry for cancelling last minute. Doesn't offer to reschedule. This definitely seems a little weird.

She starts to text me noticeably less and less from here on out. I basically just ask her when she's free everyday, but not much else. We go a couple of days without texting and I break frame, texting her some stupid meme and how it reminded me of her. She sends me a one line response, I text her back, she doesn't say anything.

She texts me 36 hours later, so at this point I'm getting a little fed up and straight up say "come over tomorrow for dinner after work". She agrees.

She comes over, and in person she's enthusiastic as ever. I make us dinner, we fuck and its great. She's happy, gives me a long hug before leaving, and heads home. Texts me when she gets home, I reply and then forget about it.

A couple of days later I text her some sexual shit like I can't get her body off my mind, she says something like "Haha, you're welcome" and that's it.

The next day I ask her if she's free the following night and make a comment about a TV show we watched.

She responds 36 hours later, ignores my text about making plans, and says "youre welcome for introducing you to the show". I reply, and get no response.

It's been 4 days since and at this point I feel like I've been ghosted. Beyond the oneitis and the fact that I dont have abundance, I want to treat this as a case study for how I could have handled and gamed this chick better. My theory is that she probably found another dude off a dating app with higher SMV and started riding his dick instead. I'm kind of confused as to how she goes from insanely high interest to completely ghosting me in the span of three weeks.

TLDR My first plate is very interested in me, can't keep her hands off me, keeps texting me, but slowly goes ghost on me. How could I have gamed her better?
