<human>: Can you condense the text into three sentences or less?

Recently my girlfriend and I are having a lot of fights (mainly because of me). This is because i feel that she is asking way too much time from me. We talk like 2 hours+ a day. It doesn't sound too bad but its really clogging my time that i need to study and do my own things. My time is about 5 hours ahead of her and she has on job training at the moment so she mainly calls me around 11.30 at night  and/or 10 am in the morning.

The thing is, i feel that our relationship should have moved on to the phase where its alright to idle chat about random things because we know each other very, very well, and have free reign of our time unless something important comes up (were pretty much bestfriends too). She gets upset when she feels she doesn't talk to me enough and we end up fighting.
<bot>: My girlfriend literally spends 90% of her free time on me and it has been starting to bug me, what should i do?
