Should I still send him memes and stuff? Or does that too sound annoying and desperate on my part?

My best friend used to speak to me even when he was back in his hometown but now he doesn't. The first time this happened was a month ago. I asked him why and he said he never does talk to anyone when he's back home, that he wants to spend time with his family. But he never did that to meeee, only other people. I asked him what if it's urgent? He said he still wouldn't pick his phone if it was an emergency. I just stared at him speechless.
I'm not sure if he's trying to create some distance and slowly detach from me because it's true that I'm a handful, I've already had 3 outbursts in our 1 year of being friends. That too in public. I'm know it's a no-no for anyone. That or I'm just overthinking again and this is my borderline speaking to me, because it's fair that he should spend time with the fam. I will never understand what's real and what isn't.
If it's true that he wants to create distance, and not my head messing with me, then should I even care to send him memes like I usually do? Because I don't like silence in response to me remembering people in my happy moments. It's insulting and makes me feel pathetic. It feels a lot like social rejection.
But if it's untrue, I don't want to ruin things. I've lost friends in the past to borderline.
