Sharing Our Innermost Thoughts

he hasn’t texted me in 24 hrs
it’s the case always
if I don’t message first we don’t talk for days
he’s acting wierdd too since a few weeks
he had crush on me months ago
which I rejected but we became good close friends afterwards
I understand he has College and job and family problems
but he never texts first
like when I do he’ll come online in seconds and be veryy energetic
but idk he’s changed now
I don’t feel like messaging first this time too see how many days we can go upto without me texting
he says goodnight suddenly and disappear…and when I ask he just replies " there’s nothing, I’m just tired" as if he’d offended by something I tried to ask few times
he has the constant answer
before that we used to talk late night till 2-3
I don’t know what to do
