We were confirming our plans for our date tomorrow and he's usually pretty quick to reply unless he's at work. Tomorrow is the first time we're meeting each other. The last message he sent was " you're actually going to give me a shot with you right?" to which I replied, " I mean, I'm going out with you tomorrow" and he hasn't even opened my chat but his snap score is increasing. I'm usually the one leaves him on read, until he messages me again asking me not to. Should I be worried? Is there any reason why a guy would deliberately ignore your snap but open/ respond to others?
