Am I (18M) missing the signs from my friend (18F)?

Am I overthinking this?

So I met this girl in my class about a month ago, and we began talking on Instagram. She seemed into the conversation, and it carried on well, and into our in person talks as well.

She actually suggested we hang out first. On the first date she mentioned she was still talking to someone, but later after we hung out she told me she broke it off. From then on we’ve hung out maybe 5-7 times, and I feel like it’s been nice, but a little awkward and quiet sometimes. She does still suggest another hang out sometimes, but I feel like I am initiating more now (I’m fine with this I just don’t wanna seem pushy or anything).

During class, she showed me how her earring was bothering her, and asked me to touch her ear. (Little weird but sure I did)

Throughout this, I’m not sure if she’s still talking to the guy mentioned before, and we haven’t talked in a few days and usually we sit together but haven’t for a few times now .

I’m not sure what to do because I like her, and I want to keep being friends, but I’m not sure if either she lost interest or is avoiding me or something, because she seems less and less enthusiastic.

Sorry it’s long is just like some advice from another perspective. I don’t want her to think I’m pushy but I don’t wanna bother her if she’s not interested anymore.

TL;DR - I think girl is sending mixed signals, is she interested? I want to ask her out but some advice pls.

Thanks for any advice !!
