She knows you're interested, if you text her too much it will definitely come across needy. There's no reason why she can't get in contact with you once in a while!
There's a few girls who I was texting quite a lot, and met up with a few times (f-closed one of the two), and our contact died down, so I just thought 'fuck it, I cba, if you want me, chase ME for once', and both of them within a month were back texting me saying they missed me bla bla.. it really plays into your hands.
What i'm trying to say is, i'd play it smooth mate.. everyone loves a chase and to be kept on their toes.
EDIT: Just noticed you said you're going to try and arrange for this weekend.. if I were you i'd text/ring her tonight, and just say 'listen, i've got quite a lot arranged this weekend but i'm sure I could fit you.. say _pm on Saturday?' or something similar, therefore you're telling her when YOU'RE free, not waiting to see when she is. If she can't (and there's a good chance that if she's very interested she can make time imo), then i'd hit her with a 'ah, too bad, nevermind then!

' or something like that. The less concerned you seem, the more mysterious you'll come across.
This may sound like bullshit. I'm not a PUA
