So I'm trying to get my ex back (I've posted a few things on this topic).
I've kept screwing up, and went sorta burn it to the ground pushy. It's uncharacteristic for me, but I really like this girl (why I keep fucking up). I broke up with her (stupid), and she has been seeing another guy. I've seen her twice, and talked to her on the phone two times in the past month. I've had a few texts, some coming off needy.
I removed myself from the situation for two weeks, have been hanging out with other people and working on projects. I'm more or less back to emotional baseline.
We made out two weeks ago, and I nearly got her back (she said things like, "I've really missed your eyes", did the "What are you thinking?" while looking deeply at me, and other things like that). I haven't fucked her in quite a while though (a big problem of mine, but I don't want her to feel "slutty" - but I think I should get over that).
I think she may have wanted me to tell her I loved her? But that seemed dangerous.
I texted her the next day after making out with her about how I wanted to eat her out so bad, and then I kinda tried to push the subject.
At first she was like, "I LOVE IT!!!

"
but then after a day or two (of somewhat pushy/needy texts from me, sadly - it has been difficult to control myself, I'm not used to being emotionally caught up in a girl, usually I'm cold and don't get attached) she was like, "We're supposed to be friennnnnnnds" and then I called her, acted weird and she said that maybe we should not talk for a bit, which I've honored for two weeks.
She posted some stuff on my FB a couple days after, and has liked some stuff of mine.
I've fucked this up pretty hard, but she still seems to like me somewhat. If she wasn't seeing this other guy, I'm sure she'd give me another shot, but getting her back seems tough. I wouldn't normally put this much effort into a girl (I never do) - but I think this one has serious long-term potential (we're both at about marrying age (we're both 27, I turn 28 in like 3 days), but I broke up with her because I told her I wasn't ready for that sort of seriousness, and I'm only so-so on kids, and my bitter 34 year old female friend told me not to "steal her breeding years")
I'm releasing a children's book (which she has helpedo n as well as a social networking/ecommerce site this weekend (right before my birthday). She knows and is excited about the children's book (but likely doesn't know I intend to publish it this weekend). Almost nobody knows about the ecommerce site (which will be pretty involved, involving apps, LinkedIn style contacts, and a Facebook-like wall).
Can I use any of this to recontact her and get past the neediness I showed? I know the usual advice is, "GFTOG", but in this case - I can already do that, and I don't really want to. I've slept with over 30 girls, and I like this one best.
I don't really know that the PUA forum is even the best place for this sort of question, but hey, it's a start.
TL; DR:
I showed quite a bit of neediness to a girl I used to date. We've been making out within the past month, and I'm releasing two major projects (a book and a website) that are going to come off as pretty awesome. She's dating a guy, and seems to like him, but she's considered coming back to me recently (two-ish weeks ago). I then went on a very needy kick and pushed her away. I wouldn't go after her so much (I've dated plenty), but she's far and above the best girl I've dated so far.
Is there a way to get past the neediness I showed? Possibly at a time when I am comparatively awesome, like after releasing two major projects?
How do you recover from showing neediness?
