If you're spending this much time thinking of one specific girl, then yes that means you're lacking abundance. Think about it this way, you have 4 girls who are 10/10 always trying to get a date with you and fit themselves in your busy schedule.

Now you meet this other whore and her responses are lukewarm. Do you continue pestering her over text? Or do you go gravitate towards the ones that are showing the right attitude?

Even if you don't have 4 hot models waiting to drain your balls, you need to act like you do. If this bitch is not giving you the right answer then you SOFT NEXT her, you will gain nothing by pestering her over text, if anything you will turn her off even more.

Your best bet is to go game other girls. If you're not replying to her she will understand you are higher value than some stupid beta orbiter. Depending on how the date went, and the current circumstances in her life, there's a chance she'll text back at one point and say she'd like to go out again and you might have another shot. There's also a chance you'll never hear back, but who cares because there are billions of women on this planet. This is how you should deal with all women who are lukewarm, some will actually turn around when you give them the cold shoulder and others won't which means you won't be wasting precious time with them.

Edit: I misread that as "I fucked up during the date". Mate if you fucked her during the date then you have more power now and you need to act more aloof, how long did you wait after smashing her puss to text her? I hope you didn't send her anything the next day.
