Talking to my boyfriend

this is probs gonna be long. so me and my bf have been in a long distance relationship for a year now and only dated for two months before he left. he live in hawaii and i live in virginia, so the time distance is 6 hours (7pm for me 1pm for him) so it’s already hard enough. i feel like i can’t talk to him about anything bc anytime i mention something that bothers me, he laughs it off and genuinely thinks it’s funny something so ridiculous could bother me. and now i’m having some family issues and when i went to talk to him (my best friend) he takes forever to respond to me cuz he’s busy. he is never there for me when i need someone to talk too. i even went to a friend and him with another problem and got a empathetic respond from the friend and a “sorry that suck” from the bf. idk what to do. i feel like i should be able to talk to him confidently and that he needs to understand that not everything is perfect on my life and i need him to give me more emotionally. idk what to do about him, i really need advice from people who have been in relationships so if you could comment i’d really appreciate it!
