Just need a rant

So my husband is away on a stag do in Poland, told me on Friday he hated it there, was missing me loads and wishing he was with me instead, fast forward to today, rings me two hours before his flight asking to stay another night with some others as they haven’t spent much time with the stag. Unfortunately it hasn’t panned out and they are flying back tonight but I can’t help wondering why the sudden urge to stay when he wanted to come home so badly 3 days ago, am I just reading it wrong or does it seem a bit dodgy to anyone else? 😕
