How should I handle the fact that she has this opinion?

So my boyfriend of a year left yesterday to a city that is 4 hours away from where we live, for 2 weeks for his engineer job, I even got emotional and cried, cause we have always been together, not even a week apart, this job he has, is new, he started in 2018, and last year he did not travel at all, so I guess that this year he will travel a little more, I don’t know.

How can I cope with this, I been living with him since December, before I lived with my grandparents, which are abroad and left me their apartment in charge, I was in our house until yesterday, and yesterday he brought me back to my grandparents apartment, I feel safer here, I’m a little scared of being alone in a house, for some reason I don’t feel safe.

So my aunt was talking with me yesterday and was asking me if he was going to call me while he was away, because that is what every normal couple does, if the man is away he should call his woman and check up on her and she told me: I will be honest with you, if he does not call you then he is not interested in you at all, it would be abnormal if he did not call you.

My boyfriend has been excellent with me, and she even knows he is a great man, so I don’t know why she said it like this.some other people would say, every couple is different and they will do what works better for them, but my aunt insists that every couple calls each other everyday.

I know that she will be asking me:’’ OH DID SO AND SO CALLED YOU’’? I know her, and I don’t know whether to tell her the truth or just tell her all the time that he in fact is calling me everyday.

To be honest, I found this comment she made very abrupt for some reason, she is to some extent right, but I don’t think he has to call me every single day.He is working hard on this project, it’s not like he went to have fun or something.By the way I am not trying to excuse him, I am just saying the truth, he went for his work.

what do you guys think about all of this?
