My Gf goes to an all girl college 8hrs away..

i’ve never been in a LDR and well now i am for the first time. this first week they have a bunch of different parties and things they go to to meet friends... so basically she’s out a lot at night. during the day.. she’s usually just chillin in her dorm or outside talking. when she was here with me, we would always facetime or text.. but mostly facetime. now i have to ask her if we can facetime and most of the time she says yea but after she gets back from a party or some other event. i say “okay” and wait up til 1-2am.. when she finally gets on the phone she’s never alone so i feel like i can’t talk to her the way i want to.. or whenever we just get on the phone someone always pops their head in inviting her to their room to play a stupid game. she always says yes and goes so now i have to wait to talk to her. last night i told her i wanted to tell her what happened today and that i missed her voice. she said she missed mine too and that she’ll call me when she gets back from the party (which will be around 1-2am). i said okay and waited up until finally i started to get worried when she didn’t call me at 2am. i asked her if she was okay and she said yes she is.. she’s just outside with her friends... while i’m waiting patiently... and exhausted. i got irritated and said i’m just gonna go to sleep and she asked if she could still call me when she gets inside.. i didn’t answer and she ended up calling 5mins later. i was irritated with her but i couldn’t stay mad at her because i really missed her and hearing her voice made up for it. as soon as i thought i could finally talk to my gf ALONE.. i heard another girl in the background talking.. i got irritated again and started giving her short answers hoping she’d realize i was upset. she didn’t need up realizing at all. i said in my head, well when she goes back to her room to sleep i can talk to her about the important stuff and then she ended up sleeping in the girls room with her in the bed.. a twin bed. i just don’t know what to do and i need advice. i understand she’s trying to make friends and trying to have fun but i miss her and i just want to hear her voice and see her beautiful face for at least 30mins alone each day. i’m happy and excited for her.. i just feel lonely without her.. she’s literally my best friend and my gf so chillin with my other friends isn’t as fun... if anyone has any advice please don’t hesitate to comment.
