Need. More. Attention.

how do i get my boyfriend to pay more attention to me? he lives an hour away, and we're both busy on the weekends sometimes so we haven't seen each other much lately. we used to be perfect together, he would text and snap me when he wasn't working but now it seems like he is playing games and ignores my texts for days at a time, and he replies to other people on snap but doesn't open mine. i don't want to confront him about it because i don't want to seem crazy and like i need a ton of attention, but i do lol. should i ignore him back so he wants to talk to me more? or what should i do?
