Little bit of love

I found this crazy unique girl who I never thought I'd end up falling in love for, I've only seen her since our date and I really want to see her again, I'm seriously in love with her and shes  captured my heart but... I'm not too sure about her...
I send her texts day and night reminding her I'm there, where as she's  always at someone else's house  I feel lonely and sad when I'm without her... Yes I guess she sometimes makes me happy, but how can I be truly happy when shes never around?
I don't know what I'll do if this keeps up, I seem a bit clingy but i can't help it, no-one has ever made me really truly feel this way... I really hope I don't end up losing her I just don't want to end up like that again.
