What's the appropriate action to take with girls who flake, but then reapproach later (both those with a high chance to flake again and those with a low chance)?

There are two girls:

First one:

I demonstrated SUPER high value to (I have two cars, one is a sports car, I had multiple women with me at a club when she ran into me, had opera tickets that I accidentally left in her car) but have also demonstrated low value to (texting when high on New Years, asking her if she wanted to hang out a few times) - and she's sorta wishy-washy about wanting to hang out with me. She made comments about hanging out when she was in town this past weekend but I sorta poo-pooed them. We were supposed to meet up at some late night club but her "phone died".

My initial thought process is ignore her, game other girls, reconnect in a few months.


Second girl:

We met up, drank a bunch and fucked. I was a bit of a pussy with text messages (ongoing problem I am fixing). She kept being busy or having something to do (while she was posting about going on dates with other guys). I texted her 3 times to hang out (which is once more than normal with girls, but I liked this one and we had fucked so it felt ok)) before switching to just sending random funny texts.

She has texted me a few times in the last two weeks, mentioning hanging out, but I was busy, and drunk respectively (I'm cutting back on alcohol intake, I've been acting stupid this month), but I'm also hesitant to hang out with her because she absolutely ignored me for two months (well, she responded to texts). But the sex was good.

How do I hook up with her while maintaining my self respect? (presuming I don't get shit-faced and act like an ass again).

And yes, you don't even have to tell me I need to control myself while drinking - this has been poor form this month. Typically I'm better. When I DO royally fail with a girl I am doing good with though, substances are usually involved.
