I (17f) need some help on what to do with this situation

My friend got the @ of a person I found attractive in public, I did contact them and we started texting we even made plans to go out but they would always get canceled (I was aware they had a job and they were very busy) I would always get left on delivered for long periods of time too but it didn’t bother me that much until 2 weeks later of texting it started to stress me out i realized later i was being too clingy and i was holding on to hope that i would be able to be with this person because their was like a spark when we first started talking like they would text me first and try to make plans with me but then like 2 weeks after that it felt like it became one sided and i was forcing the conversation. I just got really mixed signals from them so I just told them one day i found them really attractive and then after their response I just left them on seen and we haven’t talked for about 2 weeks now and it keeps getting to my head i deadass fumbled this and now it feels like I cant find anyone else attractive at school and i usually have multiple crushes but now i’m just stuck on them. I’m planning on texting them again during the summer so we can hangout because currently i’m working on myself and focusing on my goals but i don’t know if that’s a good idea to reconnect with them again but i really feel like doing that and i’m trying to figure out why, i would ask my friends about their opinions on it but they don’t know that i still feel this way towards this person. I don’t know if i should go back to them or never talk again, I haven’t felt this way like ever and this is my first time finding someone attractive out in public (school doesn’t really count i think).

TL;DR – Started texting someone that my friend got the socials of in public, after 3 weeks of mixed signals and making plans just to be canceled, I open up about the way i find them attractive, we stop texting after that. It’s been about 2 weeks since we’ve texted. I wanna reconnect with them when it’s summer again but don’t know if its a good idea.
