My boyfriend would rather hang w/ his friends than talk to me.?

Mk, so, my bf would rather hang out nd play bball w/ his frends then talk o me on the fone. I always ask him if he wants me to go and he usually says no but sometimes he says uhhmm yeah ill call u back soon and calls like after 1 hour or 30 min. Im not that clingy tho we text 24/7 but mostly talk on the fone more than text...hwta do u guys think& what should i do? I dont plan telling him this tho
