This is important information. As important as you are, he probably had a lot of things on his mind. I think it's understandable that he took a long time to contact you.
But he should have told you something like, "Wow baby, I'm sorry I should have txt'd you sooner. I've just had a lot on my mind because of my mom's surgery and everything, but I'd still really like to see you."
I really don't think this has much to do with deaf/hearing differences. It's a matter of basic relationship communication.
