Should i apologize to him?

i think you do need to stop playing so many games, and you do need to answer your phone if he's calling or at least call him back. I would maybe send him a short message apologizing (if it's multiple pages, it can become creepy), and if he doesn't answer back, forget about it. I don't think he was totally right to call you sick though and to stop texting him. If you texted him a lot without any answer from him, then yeah, you might have been better off not texting him and he hinted that he didnt want to talk.
