So, I met this girl last year. A few months after we started going out, she made spining plates much less enjoyable for me, to the point I felt I was doing so as "an obligation" (at this point she was a FWB, not a plate anymore).

At first, I felt that I was the one pursuing her, but as she bit my bait, things turned around and she was the one coming to me. Last month, she opened up about her feelings and so did I, and we decided things were going to get serious between us (but I still haven't asked her to be my gf).

Ok, so after the talk she said something like "I never tell you stuff about my family or my job, because you don't seem to care. If we're going to be in a serious relationship, you're going to be the one I'll talk to about these things, so this must change". Yeah, we really never talk about heavy stuff, and fuck, I don't want to deal with her problems, I've already got mine. I kinda agreed, but this was a gamechanger and I felt a bad feeling in my stomach after she said that. Also, 2 weeks in and she's complaining about how I don't answer her messages for 6h (yeah, because I focus on my work, unlike her), so stupid.

So, she's pretty, we're both engineers, she has a good career, she's as crazy as me, enjoys trails/beaches and is never bitchy about it (unlike my former gf that started crying when a tiny toothless fish "bit" her). Those are fine traits, but I know she's no unicorn. My question is: is it normal that when I finally got her I don't want her anymore? Too early to let her go or should I try a little harder?

TL;DR: met a girl, pursued her, made her pursue me. Now that I got her, I don't feel I want her that much. Why is that?
