couple ghosted after one play and im trying not to take it personal

had what felt like an amazing night with a couple in glasgow, four hour meet at theirs, chemistry with both of them, she said multiple times during and after how much fun it was, he was relaxed and inviting, we all hugged at the door and said "lets do this again soon"... and then nothing. messaged after a week to say thanks again and float a follow up, got a "yeah we'll be in touch" and now 6 weeks of silence. is this just standard couples behaviour and i should let it go, or is it worth one more soft push, or do i just have to accept that ghosting is part of the deal even after what seemed like a great connection. im not heartbroken im just confused
