Ok, so I saw him last night.
Things seemed fine. I brought food and he kissed me as soon as he finished up his last work call. He seemed happy and giddy and we watched a terrifically stupid action movie (transporter 3, seriously, so bad) and he goofed around and asked me for kisses and poked fun at me etc as per usual (i give it back too)
He mentioned changing plans to see a guy friend of his (they play D&D every few weeks or so) on Saturday and then confirmed if Sunday would be good for me etc.. pretty much as soon as I got in. So that was appreciated.
We didn't really have a chance to talk, since he really just seemed exhausted for the most part, and all in all it seemed like a bad time... but he did make passing comments to things i'd say about picking out a movie or whatever "oh... you will, you'll be back

" etc etc... and just normal things about getting more of the good coffee for next time.
He did seem overall pretty physically exhausted though. But there was normal affection and cuddling and this morning seemed just fine too, and he commented again about seeing me on Sunday and was affectionate as per usual.
So apparently his parents have been on him about planning a trip to take care of his grandmas ashes (FYI, this was a death that was a long time coming - and he didn't care for her, neither did his parents etc etc... so that wasn't making him depressed directly or anything ... if anything it was a load off his shoulders) and fly out to his uncles ranch etc etc... and he has no desire to take as much time off as they want him too... so it's been a bit of a pain in the neck...
He's also been busy at work, and it seems like he hadn't been getting much sleep for the last 2 or 3 nights and has just been all around stressed.
So... while yesterday was slightly off, as he seemed tired, he seemed happy to see me and spend time and did quite a few things that one wouldn't do if they were getting to the point of ending it.
I am still going to talk to him if he continues to act this way obviously, but I figure i'll give it a while, and Sunday I might get a better idea of what is going on and if it is just stress/work etc or something else and then we can talk.. during the day instead of after a long day of work.
I still have my concerns, ... and will probably be a bit nervous for a bit, but there isn't really anything I can do about it except for relax and let things happen.
