pete is right, keep an open mind. you dont know for sure what's happening with her right now. though, whatever maybe is her reason, it's not an excuse not to contact you for two months. she can find ways even if she doesnt have money. if in case she lost her phone and havent memorized your number, there is the internet. email address is easy to remember. there are a lot of ways to keep in touch whatever the circumstances we are all in.
just what my mom used to tell me, "If there is a will, there is a way."
I hope you'll hear from her soon.
