Pllleeease some help!!?

my bestest friend is of the opposite of me. I've never seen him in 'that' way before. But there was this night he was over at mine, he was acting strange. He was on my computer when he abruptly said he had to leave. We said our goodbyes, then about half an hour later he texted me asking me to go online, when I went on my computer there was a message left on there saying su nuestro tiempo. Now I don't speak any other language but it looks like spanish to me, I have no idea what it means and I dunno if I want to! But I guess I have to, right? Anyone have any clue what it means? Would be very, very helpful. ooo im actually very scared!! haha
