I'm good with the GAL while he's gone. And I'm planning to go be with him over the weekend(s?). Our agreement was that he would no longer travel alone, period. But I can see that it's just not realistic for me to take that much time away from the kiddos.
I wish he could adjust his position in his company, but he's the only one who can/will go. I've tried to encourage him to look for new employment, but he's happy and secure where he is--he likes what he does, is self-directed and is nearly untouchable when it comes to politics and others trying to boss him around.
As far as OW, he says she has a new job and honey, and her MySpace page confirms both points. I don't think that means she (or anyone, really) is out of the picture forever, but what he's said to this point is believeable.
H is continuing to do nearly everything I've ever wanted from him. He's been at it steady now for four months without any real deviations from his attentive, present, relaxed behavior. I AM THANKFUL FOR THIS! I still have worries here and there that it's all just an act, but I don't know if I could keep it up for that long if I didn't really mean it, you know? So I'm just going forward, day by day, watching and enjoying and remembering that ultimately, I'm the person responsible for my happiness.
