What to do about growing apart in long distance relationship?

My girlfriend and I are in a super long distance relationship, as in she's in another country that I cannot drive to and would take 5 hours by plane. First it started with us talking everyday, texting a lot, emails, skype once or twice a week. Lately her phone broke and she is not even interested in getting another one, so we don't text, talk, and for the last 1.5 months we haven't even skyped. So it's been about 6-7 weeks since I've seen her face or even heard her voice. Our only form of communication is email which she doesn not even check daily. So we talk by email a few sentences about 2x a week now.

I feel like we are just drifting apart from each other, I mean I love her and she loves me but is that enough to not have contact with one another for so long? this is also going to be a long distance for at least another year about so nothing soon. I tried to visit her for a weekend but she says for the next few months she's too busy with school to have time for me to visit.

I want to tell her how I feel but every time I say something about missing her or just wanting to be with her, she tells me to be strong and how she needs a strong boyfriend otherwise this won't work. So basically I can't even say anything about this whole distance and how it affects me or I'm being a pansy in her eyes. What the hell do I do because I don't know if I can go the rest of the year we have left without at least texting everyday. Right now if I want to tell her something I have to email her and wait like 3-4 days for her to respond, and not being able to tell her something instantly is driving me crazy.
