My boys return from trip with dad

My boys returned from a 3 week trip with their dad last on June 20th. I thought I'd either be happy because they had a miserable time or sad because they had a great time and I wasn't part of it. Neither scenario came to fruition. I picked them (meaning my ex and my sons) at the airport Friday night and all of them were quiet. None of them wanted to share much about their three weeks in Europe and I wanted to respect their privacy so I didn't probe. I thought that the boys would spill their guts after we dropped off dad but, that was not the case. Over the last week I have heard some stories but, when asked, the boys say they had an "okay' time. I can't get upset with missing "okay" nor can I be happy that it was just "okay" so, I have accepted it. My sons spent three weeks with their father on a trip and it was "okay." And you know what? I'm okay with that. Life doesn't have to be lived in the extremes, sometimes it just is.............
