My online Gf

I have a girlfriend that lives in Australia she is Filipina and I live in the United States we've been online dating for 2 years now and she drives me absolutely crazy lately.. if I'm tired and I want to go to sleep she still keeps me up and video chat and I keep hinting and trying to say that I need to go to sleep to go to work in the morning but he still ends up talking and keeping me on and it s usually just random silliness trying to teach me to talk het language in other things that are just we have two totally different times and I keep having to stay up till 5 in the morning and I m going to work exhausted and she never really understands every the last time I tried explaining it to her she thought that I didn t want to talk to her that I don t care about her and she always makes me feel that way I really don t know what to do.. but she is sweet and kind and I feel so bad.. so today I uninstalled my app and just disconnected myself from her without any warning or explanation.. I didn't want to explain because she will only make this harder..and make me feel bad, but I have a life to live and I will never be able to go to Australia because I work 10 hours a day.. did I do wrong?
