So my DP (46) does a cold lake swimming with a group of women. He is the only man and ladies are in the range of 40-70yrs. He got into the group through the lady he met through my son’s sport. I never met her as I’m at the different sport with my DD. So my DP called me today when I was at work and told me that the group is going to a charity event in the evening and someone pulled out, they need someone to fill the space, and if I would mind if he goes with them. I really don’t care tbh as my DC are with their dad tonight and I’m just happy having a me time. So my DP just send me a photos from the event and it’s not a charity event! It’s a silent disco😂. I googled the location and the name of the event that was on the banners in the photo. I don’t know why he lied. He doesn’t go out a lot and I don’t mind when he does go out. We don’t live in ‘each other’s pockets’ and are independent with our interests so I don’t understand why he lied. I don’t know if I should just leave it because I’m not really that worried or should I actually be worried about it and question it when he gets home?
