<human>: Can you give me the gist of the text in a nutshell?

my SO (26/m) is away for the week on a business trip. we talked for a bit for the first few days but i did not hear from him at all yesterday (no call, text, e-mail, etc...)

i am not paranoid or upset because i'm sure he's busy but even if he's busy, i'm sure he can squeeze in a quick "hello" if he wanted to. i don't want to contact him first because he might be working or doing something important and he knows that.

so i came to the conclusion that he was so busy with his work yesterday that he just did not want to talk to me.
with that said, is this normal for a relationship (we have been together for 3 months)?

with all my previous boyfriends, there wasn't a day that we didn't hear from each other so this is definitely new for me...
should i be concern that he is not that into me or not that interested in the relationship? i have to question it because if i were away for a week, i'd try my best to make some sort of contact with him everyday to let him know that i'm thinking about him.

if he's busy and thinks not talking all day is okay when you're in a relationship then i'd be happy with that. i'm just concern because i don't know if this is a bad sign...
<bot>: bf of 3 months did not contact me all day while away on a business trip, should i be concern that he's losing interest or is just not that into the relationship?
