I (18ftm) texting with 20m, and things seem fishy

I'll just copy my comment over from r/gaytransguys ..

"we countinued texting and yesterday his accounts supposedly got hacked and he blocked me .. and then unblocked and blocked and unblocked.. supposedly the blocking was done by the one who got into his accounts... I'm not so sure if this all is legit, cuz i asked him for his phone number and he said "a shit i dont remember it, ill text it to yout tomorrow", and tomorow is now, today.. and I'm still waiting .. i decided that if he wont text me his number untill the end of today ill block him and just go on with life. "

We talked the day before yesterday, over discord, and i didn't get the feeling of it heing fake, his dad even cam into his room and was saying something .. we all spoke in our mother tongue .... but this above is making me feel suspicious... Any advice? ..
