Are my hopes possible?

Aniston

Me and my boyfriend are dating since end of February. He would do everything to show me how he loves me and i saw his eyes that he did. We saw each other everyday in school and everything was great, sex life, and our relationship life. We had everything like other couples do while dating. On June 19th i unfortunately had to leave to another country and im here until August 14th. At first in June everything was fine, we talked everyday and he was sweet to me and everything. Starting July 10th, we started arguing a lot about little things, everyday we would argue. Then a week ago we argued, and right after he started saying how different we are and that we always been and that we always argue (which is not true bcuz we barely did when i was there with him) and how it would’ve been better if we broke up for the time im gone and saying how he would prob be with other girls and saying a lot of hurtful stuff but at the same time saying i dont wanna hurt u and i care about u and i love u and being very like “yeah im breaking up with u later”. The next day, i got sick and he was sweet like nothing happened. Then texting me saying

“Babe, wanted to clarify, i really want this to work out, its just sometimes i dont feel the same, but i miss you and care about you so much” after that we were okay and he was sweet, then 2 days ago again, he started being very cold over text and he stopped calling me babe or saying i love you and when i would say it only reply with hearts.

I was facetiming him today for the first time in while since we fought. He was talking like im a friend, he was acting normal but calling me by my name instead of babe like he always does, and i kept asking if he is exited to see me when i come back and he is like “yeah” in not that exited tone in my opinion, and i said i love u before i hanged up and he is like yeah “i love u too” and hangs up. He wore the bracelet that i gave him before i left though i dont know if that matters. He was doing stuff while we were ft so idk if thats why there were barely any emotions. My dad said its normal for a guy to act like that who loves a girl and she has been taken away from him just like that from being everyday together and bam im gone for a long time. My dad said its just its hard for him thats why he starts saying all that crap such as breaking up and other cold shit, and being cold in general is okay because he is suffering. My dad was saying all of it bcuz he acts the same like he said when his gf leaves and he actually loves her. I hope what my dad said is true and i hope that he still loves me. I hope it will change when i come back and reconnect with him bcuz i feel like we are disconnected i dont know if thats a thing but yeah. Dad says it will be different from the second he sees me in person and that we will be close again. I hope it is true bcuz i love him so much. Please share your thoughts on this bcuz i need some hope that we will be okay.
