if you go for her it's gna be like a minefield. always watch your next step, but before you go through think first if you could make her life better compared to your friend. if you could do better and shes worth it then go for her. just always watch your step

if you wait, it's going to be torture until someone bails you out, the pain will depend on how much you like her. since shes only a crush to you then it would bearable. unless you have deep feelings for her already then your life would suck.

check for signs if she likes you or not, like if she smiles when she talks to you and all of those other things
