Yeah the only reasonable conclusion I can draw from not kissing is that she isn't interested romantically anymore. Else I have no idea why you wouldn't.The fact that you two went from making out and cuddling to being rejected just a midnight kiss makes it seem there is more going on here with her. Maybe she doesn't feel romantic towards you anymore. Maybe she was having a bad day. Maybe she's got someone else. Either way, I'd leave it up to her now to whether there's another date. You could ask her plainly that you noticed she went for a hug instead of kiss, how come? But if I were you, I'd take that as a rejection and let her text if she's still interested. This will give you peace of mind that the responsibility is off your shoulders to take this further. Have you got anyone else lined up for dates? If so, focus on them and keep her in the background for now.
And yeah I have a date lined up Wednesday so I'll focus on that for now. Thanks.
