I’m really hoping for some perspective here. We are currently in Spain with my friends for a holiday. It’s us ( myself, DH and DC 14,16 ) and my friends ( Kate, Neil, DC 14,17) obviously names are changed. Kate was my friend for a few years through the activities. They invited us for a holiday with them. We booked two different villas about 5min walk from each other and right on the beach. Since we got here, Kate and my DH are spending more and more time together. This is our full third day here, and so far today, they met running at 7am and booked a spontaneous paddle boarding for themselves at 10am. We were all on the beach later and went for a lunch. I went back to the villa to get some plasters and they both turned up. My DH said he is changing his top as he and Kate will walk to the town to get a few bits. All of the DC are spending their time on the beach learning windsurfing with the local club so I don’t need DH to help with childcare. Kate’s husband Neil has a work project to do so he spends about 5 hours a day working in their villa. I’m starting to feel like a 3rd wheel to my friend and my DH. I’m getting grumpy when I’m around them and I don’t want to push him away but I don’t know how to get out of this mood. And another thing which got me thinking is at the dinner, Kate asked for a sparkling water and my DH said he wants some too. He never drank fucking sparkling water but when I pulled him on it, he said it’s because I only drink a still water so he did too. So for years you were drinking still water because of me? Have a sparkling water if you want! Something is feeling odd and I can’t put my finger on it
