<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I met a girl on OKC back in June. We had a great first date that led to many great dates. She was one of the first girls who I genuinely liked and the feeling was mutual. Over the last month, things felt different. I felt like she was losing interest in me. When we would hang, everything seemed fine. But, when we weren't hanging, there would be this weird vibe. I brought it up to her last week and things broke down. She said that she doesn't feel a spark and that there's no 'passion'. I told her that maybe we should take a break and the night ended there. 

She later texted me saying that she really likes me a lot and liked how nice I was to her. But, she wasn't sure how I felt about her. When I said that I really did like her a lot, she said that she was upset cause things could've been fine and she doesn't want me to disappear. After not talking for a bit, she said that I thought I was looking for something serious while she was looking for something light and fun. She said she misses me and wants to hang. 

I do want something serious but I also really like her and want to keep hanging out with her. I've felt like poop over the last few days and I'm not sure what to do. Would I be wasting my time hanging out with her again? Is the 'spark' and 'passion' thing a serious thing? I'm kind of torn. This is my first actual relationship thing so I really have no idea what I'm doing.
<bot>: relationship felt weird, decided to take a break. she wants it to be casual, I want it to be serious. she wants me back and I'm not sure if I should.
