Gf says i dont show affection and i am using her as convieniece

Currently been dating my gf for 1year. We met in Malta in europe. Shes from Japan im maltese. Im currently studying here in kobe Japan. I decided to move here before meeting her. When i came here, she started criticizing my apearnce and my Japanese level. When we met in Malta my level was even lower. This made me feel withdrawn and i felt isolated. Instead of understanding my situation she stsrted criticizing me and saying i dont have much efferot. After that she started saying i dont understand her feelings. When she was speaking she was using kansai ben and speaking fast. As i go to Japanese language school my listening ia not bad so i understand normal daily Japanese however she did not give me time to answer her at times. I explained that i might have not been affectionate as there was a change in environment and i was honesty stressed. But despite explaining i agree i might have neglected her emotionally she kept saying its like im using her. In reality i think i paid more when we go out for her despite living on student budget. And at times just asked me to "pay" like at the supermarket or restaurant. This did not happen back in Malta when we met. She seems to have changed how she sees me despite being open to her to come over to my place have a tea and just talk slowly about her feelings

We are just talking online now on WhatsApp and honestly i explained my self why i might have withdrawn at times of stress and i was not in myself
