Found out a friend was lying about his age

this takes place entirely online

my friend always told me he was 17, ( i am 17 too). we talk somewhat regularly but not like daily. a few days ago a mutual dmed me and showed me old screenshots where he had listed his age as 21-22, so ofc i msged him about it.

he immediately admitted it and said he was actually 22. 5 years older then he told me he was.

he never tried to talk about anything nsfw or get a relationship with me, and afaik he is asexual + aromantic and not dating anyone. i dont think hes trying to be a predator? but this feels like such a weird situation. i tried to ask why he lies and he went on about how he feels weird about his age, and cries over not being younger. which i understand but you cznt just lie about being a minor…

should i like tell ppl? or push him to tell the truth? if he was lying to me (a minor) about being one, he probably lied to others as well(??)

i really dont think hes a pedo but he has a public account and kind of a following and it doesnt feel right
