Should i text her after so long?

Ik this sint my first post and i doubt itll be the last but fuck it.

Im a 16 year old dude, who graduated back in june. In Denmark, the requirment for school is from kindergarten to 9th grade although most continue with school but most places dont offer anything and a few offer an optional 10th grade. Back in the middle of 8th grade i switched schools and during those 18 months, i got pretty good friends with a girl (imma call her V) and i developed a big crush on her. We had a lot of fun together along with our three friends and i think she might have had a crush on me (long story, but im pretty torn on it. Check my other posts for every detail). During graduation we said our goodbyes and see ya laters and we just kinda fell out of touch. Life just happened ig. The problem is im still not over her.

I wanna text her and ask if me, her and our three friends could meet up and maybe hang out again but ig im afraid. I wanna reach out, mainly cuz i miss her, but i could live without seeing the rest of the group again. What if they dont want to? What if shes over me? What if she found someone else? That would probably break me. She is the closest i have found to my dream girl and i fucked it up. I really wanna meet up with her but i just cant get myself to do it (it took me 6 months and almost passed out to even ask her to hang out).
