Am i overthinking?

Greetings everyone!
Well, let's keep it short. Last year i met this girl who i KIND of found atractive. i didn't like her that much at first sight, BUT as i got to know this girl, her personallity got me crazy. Unfortunely, i realized this EXACTLY the last day i saw her (arond like 2 months ago). So she got an operation and i could only message her. I seems she doesn't text that often, but i almost always get an answer, even last Monday she "started" the conversation (and i was happy as hell). The thing is... She's like 4 years older than me, but when i met her, she tought i was 3 years older (myself), so i don't really care about it, but i know most girls do. Besides, the real thing here is... Last Wednesday i texted her about the idea of hanging out... AND is Sunday already... AND no response hehe.... My "last hope" (By calling it in a way) is that the message appears as "unseen". I really appreciate her friendship and she's a really nice girl who deserves to be with a really good man (I'm not saying me XD, but i'd love to be with her).

Any points of view? Thanks for your attention everyone

It could be that she didn't see your message. I'd contact her one more time and then if she doesn't reply after second message , accept it and move on. Good luck

I've thought about that hehe. But i try not to bomb anyone (incluiding friends and familly) with messages.
How long do you think i should wait?

Thanks

Send one today and if you don't hear from her by tomorrow she probably isn't going to reply.

THanks for the replies mah friend.
Last question (hopefully), how do you suggest i should write down that message?

I mean... What could i say/ask?
Sorry if i sound dumb or something, but i really want to be carefull in this situation and your point of view seems helpfull (please don't take this the wrong way)

I'd say that I never heard back from her and wonder if she wants to hang out
