How will she know? By you NOT calling her, sooner or later once she catches up with her work she'll realize "Hey Bobby D hasn't called me in a long time..." then her mind will start to wonder..

Think about it - you've been pretty much a borderline pest to her lately. So by CONTINUING to bother her with notes, letters, e-mails, phone calls, visits, etc HOW IN THE HELL is that going to HELP anything at all, when what she wants most is T I M E to herself?

Contact her and you're shooting yourself in the foot. For her birthday I'd have a gift sent to her WITH NO NOTE, no love letter, no card - unless you just sign it and THAT'S IT. But just get her a gift and have it delivered, without the "Oh I talk a lot of shit about I understand you need space but really I'm full of shit cause I keep on going back to my old ways and continue bothering you when it's obvious you don't want this right now" letter attached. Just a gift, with a card, that has no message from you other than your name signed, so she knows who the gift is from. No phone call, NO CONTACT other than the gift. She knows your number, let her come to you. If you contact her you're just shooting yourself in the foot.
