SOS

Lately I've been overthinking a lot idk if I should be worried or not

So me and my boyfriend are in a long distance relationship and we used to talk everyday but now we hardly talk at all he's always playing games or sometimes when we talk for like 5 minutes he then says "igtg now im going out w my friends" and then I feel sad cuz I really wanted to talk to him last time we talked properly was 4 days ago and I don't wanna sound toxic or sum it's just he see's his friends and talks w them everyday meanwhile we live far away from each other and don't even talk everyday and then I be overthinking a lot and idk what to do I really wanna tell him but at the same time I can't bring myself to tell him 

help???
