I can see where you're coming from, and it's likely you're right, but I want to clear some assumptions up:
She hasn't written me off to see other "people" (more correct term in this case, not that it matters). I came in late to the party. She was already farther with this person by the time I went on the date. A first date makes a first impression, but let's be honest, most first dates are awkward and second dates are where both people really shine if they're meant to. What fighting chance did I have? The fact that she brought me back from the dead is enough for me.
I failed to clarify she responded in kind that she was excited to see me, but built on it, saying she was looking forward to spending time together outside a theatre and being one-on-one
Am I really more invested in this? For the most part, it's been 50/50 effort wise. She texts first, I end. I text first, she ends. Back and forth. Lately, I can see there being a disconnect seeing as there's a lack of subject matter to cover considering I'm coming back soon and she'd rather see me in person. Not to mention, she came out of the blue to tell me she was moving to my town and wanted to hang out, and then was curious when I was coming back. I didn't really do much else except work off of her.
I probably seem butthurt, and I probably am, but I'm looking for some constructive criticism. Like, if you say I haven't done anything to convey my intention to escalate, how would I do that in the future and stuff like that. I'm not gonna just abandon this, and maybe it'll pan out to nothing because failure doesn't seem foreign to me at this point, but I should still give this a shot, and I want to know anything that can help me now or in the future. I don't care if she's a flake, she'll flake if she flakes, I'm used to it. I don't live around the ideal demo/psychographic to pursue the right people, so I have to work with what I got, so I can make it a learning experience.
I'm just looking for constructive advice to use later, not cease and desist advice, is all. Excuse the wall of text.
