So there's this girl I met during the last spring semester and we got to talking here and there but I never really went too aggressive on anything because I wanted to try something different, we had both effectively just gotten out of relationships so I went real slow (plus that was before I found the community). We got to hanging out once a week on the same day because our work schedules are wacky and coupled with other stuff the day we hang out is the one that works best for both of us.... and that's awesome but it's REAL slow progression. We don't really text everyday and what not but I don't really want to either, I know text game can hurt me a lot more than help me so I just aim to make face-to-face time awesome. Up until about three weeks ago things have gone real well, and we've virtually hung out on that day every week. She's real cool and definitely very attractive; I'm definitely the relationship kind of guy, think of that what you will but therein lies my biggest concern.... since we're not talking everyday and we only see each other so often I don't want to lose any relevancy and I need to at the very least maintain the attraction I've built up, I don't want the natural progression of time to kill anything, so any tips? Invite her out more, even I'd I know she probably can't make it? That seems needy.... but only coming into picture intermittently isn't good either for my goal.

On "our" day, three weeks ago, she was tied up with family business and so we missed our opportunity that week, no big deal, two weeks ago I was out of town, we miss our opportunity again, this week she's celebrating a birthday so she can't make it.

I'm trying real hard not to get oneitus and am still talking to other girls, it isn't the end of the world and I'm not hurt or feeling entitled but I just can't help but feel like maybe she's pulling away a little, told her "for some reason I wanna see you real soon, let's make that happen" and she replied with "i have a lot coming up but we will make it happen for sure" (a few days ago), I'd say we're in C3 and we're both obviously attracted so I didn't worry about "telegraphing interest" by this point.

I texted her Friday and she didnt respond, I left it alone. should I just step back, and not contact her until next week when our "day" comes back up or what?

tldr: met a girl in school, started hanging out virtually once a week after that but now I haven't seen her in 3 weeks, how do I proceed with the most effective gameplan to continue to escalate attraction and the relationship with the little time I have?

P.S. I'm still going to continue to talk to other girls but I feel like I've invested enough in this girl to warrant this post, otherwise I wouldn't even care and just move on. I certainly feel too invested to just drop it and walk away since we've both invested into each other as much (10+ dates), so I feel this post is warranted. I can definitely use seddit's help to help my progression.
