I just need to vent!

My boyfriend and I live in 2 different countries! I'm currently planning on moving to be with him! I love him more than anything! The last week he's been super busy trying to do stuff around his mom's house and helping her do other stuff and actually hanging with his friends.. Him and I use to talk all the time!!! except this last week! I really really miss him and being in a long distance relationship we need to keep communication open as much as possible to make it work! Im hopefully starting work soon and so is he! our schedules will be on completely opposite of each others and we will have almost NO time to talk and it scares me and worries me! today he actually had time to relax and instead of taking the time to just sit down and spend time with his daughter (who he only sees on the weekends) and have a conversation with me, he decided to go play a f*ck*ng video game that does nothing but stress him out and makes him rage over every single aspect of the game! All i wanted was that little bit of time to just talk to him but when he plays that d**n game he ignores me and its like hes not even talking to me!! I tried to explain to him that i just wanted the little bit of time we had to talk bc i miss him so d**n much! but he just told me that i needed to act 23 and not 10! all bc i was explaining my feelings to him and how i felt! i just dont know what to do! i want to talk to him bc i miss him so much and i know we wont be able to talk once we are both working and its gonna make our relationship struggle even more! He made me feel terrible! i warned him at the beginning of our relationship that i get these times where i get really needy and clingy and i just need him to work with me when i get in those moods, and not being able to really talk to him for a week put me in that mood! he told me when i told him about my moods that its fine bc he wants me to be!!! sometimes i forget that hes only 19 years old i just dont know what to do!!!
