How infrequent would sex have to be for you to consider it a dead bedroom?

I understand it seems like a case-by-case thing, but when I look on a large scale it doesn't sound so bad. For example would you consider once a week? That seems infrequent, but hearing 52 times a year doesn't sound as bad...

I've been together with my girlfriend for 9 years now, we are both 25. We would spend probably 2 weeks together every 2-3 months. Things were generally hectic during those 2 weeks and we'd only have sex 2-4 times, which was fine. I finally was able to move 700 miles to live with her while she finishes her last year of grad school. We moved into our apartment two weeks ago. She hasn't had any work or commitment in those two weeks. We have yet to have sex. She really has yet to touch me, she spooned me one night in the middle of the night. She acts normal and lovey and everything during the day as if nothing is different. I've lightly communicated annoyance about it but get nowhere. I've tried to initiate. I hadn't seen her in 4 months prior to this while prepping for the move. She would send me dirty texts and messages about how horny she was and couldn't wait for me to get there. Yet here I am. We are finally living together. And we haven't had sex in the two weeks I've been here......? That seems ridiculous... I want to be an apologist and say "well we did just move in" or "well the excuses make sense". When I first got there, after a 12 hour drive, it was 1 AM and she had her last day of her rotation the next day (she wakes up at 5:30 when she has work) so she was tired. That was understandable. Things have just snowballed from there......
