Falling apart 😢😭

My X told my multiple times that he still wants to be my friend. We didn't break up on bad terms. He needed time for his friends and family and to figure some stuff out. I'm still trying to recover from it all and it's still a little hard. It's been 2 weeks since he broke up with me. But I just don't understand, maybe I'm just over reacting but I'm just confused why he won't like any of my Instagram pictures? I posted one and tagged him and a few other of my friends in it. But he didn't like it. Even before we dated he liked every picture I posted. I'm just so confused, am I just acting dumb about this? Why is he doing this?
