My husband recently met a woman through a sport he follows. He claims they are just friends. My 2 older kids have met her through watching football games. They sit together during the games and have sat together during away games. It's the school holidays and he took the kids to meet her at a local park and for lunch. He didn't tell me about it. He then posted the photos onto social media sparking comments from my friends asking if everything is OK. I've told him I'm not at all happy that he took my kids to meet this woman and find it strange she wants to spend a weekday out with my husband and kids-she doesn't have kids. I've asked him how this day out came about as the sport season has ended therefore how and why are they still messaging each other. He's telling me I'm ridiculous and won't answer my questions. Am I being paranoid???
