To overreact or not to overreact, that is the question

okay so guy I like (who is also my best guy friend), is just .. being different. this is ever since I told him I like him (and got rejected hehehe)

now I'll send him messages and he reads them but does not reply. this happened like 3 times, the last being on sunday. so I told friend to message him today and see if he replies. he did. (3 minutes later)

so I was all pissy and determined to kill him, but then he sent a reply to SUNDAY'S message 2 hours ago.

I don't know if im over-reacting... or if I should be...
BUT I HATE BEING TREATED LIKE YESTERDAY'S LEFTOVERS YOU CANT JUST DECIDE WHETHER YOURE IN THE MOOD FOR ME OR NOT.

So I'm not really sure if I should swear his life, or ignore him, or pretend nothing's wrong. but im sick of having to second guess whether he's bored of me or if he really does like being my friend.

for now, I shall shut up and wait for inspiration on what I do from here
