DD was on the phone to us on speaker. I needed to pop to the loo so handed phone over to him to continue the chat, came back on and see him scrolling through my WhatsApp chat with my friend. Friend happens to be the one I have a whinge about him to as her husband is similar. He didn’t see much before I twigged and said why are you reading that but he saw her asking how he’s been and I said something along the lines of he was arsey with me yesterday but then explained why I had deserved it as I had been short tempered due to stress of various things going on in my life at the moment. He’s now gone to bed and is clearly annoyed at me. Am it the arsehole here it should he have not been looking at personal messages?
