Arranged to book a last minute holiday with a friend. We planned to book flights one weekend morning but I think they may have had cold feet shortly after - I wasn’t immediately available and got a message back saying that we could “always do another time” despite me saying I was still keen. They then messaged sporadically throughout the weekend saying they were available but then my messages were left unread when I went online shortly after (they said they were at brunch and then meeting another friend). I eventually asked politely if they could tell me whether they still wanted to go as I still wanted the days off - they responded saying the reasons for their delay was that they had spent the previous day in hospital with an ill family friend and that their plans has changed in light of all this. We are close but three were very vague with details, obviously I’m hugely sympathetic but I can’t shake the feeling that it’s an excuse (given that days earlier prior to visiting the ill friend they had already wanted to do another time and immediately became unavailable). Am I being incredibly unreasonable assuming this, obviously I have been outwardly very supportive but I feel slightly taken for a ride and really hate being lied to? I would much rather just be told that they were no longer keen or similar
