This is a follow up to a recent post I made here: https://www.reddit.com/r/asktrp/comments/804s8a/did_i_ruin_it_by_blaming_her/?st=je4wsolq&sh=82906775

As a recap, I went out with a girl, we went shopping, made-out in the dressing room, had lunch, held hands, she leaned on my shoulder in the subway, and overall had a fun time. I could tell that there were awkward silences, and I tried my best to make conversation. She is a physics major and hence is on the quiet side. We ended up banging at her place, and I could tell she was new. It felt like humping a pillow, as she was laying down like a dead fish.

Anyways, after trying to get off for half an hour, I couldn't. I ended up blaming her by simply saying calmly that she didn't do a good job under my breath as I pulled up my pants. I realized what a shitlord move that was and played it down (damage control), by hugging her and telling her she tried her best but I just couldn't get off, telling her "Sex is psychological for me anyways". I could tell she was upset. We ended the night with watching a show on TV, by which I then kissed her, said goodbye, and left.

After 36 hours I text her, and it's been 12 hours since (I've yet to hear back).

I'm planning to wait another 2 days, and there are two options for me: 1. Get the hint and move on 2. Call her and apologize for destroying her woman ego

I'm not sure what to do. I really need some advice. She's a very sweet girl. I know that if she's ghosting me, even if I apologise I won't get another date. I'm also not sure if that's the reason why she is (potentially) ghosting me, and hence I don't want to open up old wounds.

Do I just get the hint and leave without any closure/reconciliation? Or do I call to apologise and understand what went wrong?
