Me and this guy have been talking for a month, we went on a trip with our friends, suddenly during the trip he decided to act like he doesn't know me and when we came back home he didn't reply to my previous messages I sent before meeting him, so I sent him a vn asking if there any misunderstanding happened cause he seemed really weird, he said no everything is fine, are you mad or is there anything that furstraded you, why do you think I'm weird.
So I hadn't responded and I ignored him but I do really like him. How long should I wait before I text him back.
