Frustration can definitely go hand in hand with horniness. Feeling like she can't control you is good. Same with you being busy in general, implying without words that other girls are in your life, etc.
I agree with OldGuy though it depends if you slept with her yet. Because this is all about attainability balance. If you haven't fucked, she could easily auto-reject. If you've been seeing each other, you can modulate the attainability in person.
Like topcat said, pay attention to her investment level and the vibe in person, since it becomes like a reactions vs. results thing.
If you are ok playing on attainability's edge, it can act as a push-pull and boost attraction as you come back with warmth, especially in person.

This is how bad I let things get, for an idea. They have all cycled to this degree multiple times. So I guess the point is if you have already slept with her several times and she is not auto-rejecting from lack of relationship progression, you can still go on like this for pure fuck buddies.
It works for me because I like to kiss and cuddle, so some in person sweetness seems to help make up for it. But you have to give her a good fuck.

Girl 1... It's been like a week. It gets draining so I just ignore like a dick until I pop back on the radar and say everything is fine.
Like are we ok?
Honestly I'm just starting to assume that you don't want to see me but don't know how to tell me. I'm only going to ask you to not disappear on me. Please
Anyway I'm going to leave you alone. I just hope that you do get back to me
Ok one more text...I just don't understand why you're not talking to me.
Look I'm sorry. I was in a bad mood yesterday. But I still feel like you're ignoring me and I don't know why. Anyway I'm going to try and leave you alone. I do hope to hear from you though.
I really wish you wouldn't ignore the any longer. I'm hoping our last time wasn't our last time

Girl 5...
I don't even get a text after 5 days?
Merry Christmas! It's not polite to not say anything and ghost me after I've given you everything. Anyway I won't bother you anymore, won't be here for New Year so good luck to us.

Girl 5 it has gotten worse with before. So my point is you can definitely ignore the complaints. But you have to have shown her good lover value previously, and come back with warmth, like an old friend.
