help </3

helo i have this SUPER big crush on my friend but idk if i should ask him out..

we'be been joke flirting for a while now & have had the occasional kiss now n then..but like what if its all jus a silly joke ??

everything confuses me more bc recently he made efforts to learn my language & lovey terms in it and even calls me petnames in his native language..like hallo ??!!
