<human>: Can you provide a brief rundown of the text in within 3 sentences?

My boyfriend and I have been together a little over six months and he is not much of a texter. I knew this from the beginning, I'll admit. It's a big difference compared to me who has my phone on me (and replies to messages) prettymuch 24\7. He almost always calls me when he's on his way home from work on days we don't see each other, so normally it didn't bother me. But when he's away on business or visiting grad school friends for a guys weekend for example, he basically drops off the face of the earth. 

I get that he's busy with work, or catching up with friends, but I really don't think I'm asking that much for him to just text me a couple times during the day. Or for him to send me a good morning and good night text. 

Let me just stop any potential comments on him cheating, I have no reason to suspect that at all, nor do I. I just want to know from other guys I guess, do you have time/do you text your girlfriends when in similar situations? I've brought it up to him before and he'll get better but then it's like he forgets again. I don't want to ask about it again without people agreeing with my thinking. Thanks.
<bot>: what do you think, do I have reason to be annoyed that my bf doesn't text/call when away on trips  I don't want to nag without cause.
