Advice

Hey guys , hope all doing well . Iam ( 24m) with (23f) who went with each other for two dates and it went well , the main problem that iam facing is late replays from her side it's not something like more than a day ,it's like 12hours or less or more abit , and it's frustrating me , also to be honest she also asks about me and calls me from time to time and spend a good amount of time on the call, also she is in other country right now to finish her studies, should i call her about the late replays? Thanks in advance. We still not exclusive also , but i have that gut feeling that iam not a priority in her life
