<human>: Condense the text into a few key points

Basically, we're working on SO being less fancy free and me being less clingy.  He is the type that could run off for a month and not talk, and resume everything from where we left off when he got back (but he's completely faithful).  I like regular communication and struggle with insecurity and clinginess, I tend to worry when he is away for a while.

He said he was going to a bachelor party this weekend, and I did well at taking responsibility for any discomfort and just saying okay, cool, hope you have fun.  We've never come up with an official agreement on checking in when apart, and he does on and off.  This is the first time he's been away for something like this, and he left this morning and it's now midnight and I haven't heard a thing.  I tried to text and call hours ago and received no response.

Am I being clingy again?  I thought I'd be okay either way with the checking in, but the last few hours have sucked.  I'm downright freaking out that he just didn't bother to let me know he got there okay, but I DO know we had no agreement.  But I'm struggling with feeling unloved and unimportant that knowing I miss him and worry he wouldn't think to shoot me a text at any point or glance at his phone in the last few hours.  But I know some people's minds just don't work that way.

What has communication been like in your relationships?  Do some of you feel comfortable barely checking in?  Do you ever go away for a boys/girls trip for a weekend and not talk much, just look forward to reuniting after?
<bot>: SO away at bachelor party in mountains, haven't heard from him and not responding to my calls for last three hours.  Freaking out and wondering if it's clinginess on my part.
