This is why you shouldn't ignore people you actually plan on talking to in the future... You say you were busy, but you didn't tell him that at the time and people use the "I was busy" excuse all the time so he won't believe you now unless you apologize sincerely.
I can see Clear here, dear, that Tit for Tat is where he is At... He figures Now Somehow what is Good for the Goose is now Good for the Gander. In other words, he is Holding a Grudge because of you Having Had Put him on your Pay no Mind list. Give him some time to reply. If not, he is Not the right Guy. Good luck. xx
if you ignored him, he's going to ignore you. It's bound to happen, it's an ego thing lmao common sense. If a guy ignored all of my texts & then he all of a sudden answered I'd be pissed too like wtf he expects me to not be mad you know?
