AIBU to not want my DH to disappear on a sunday moring with a female colleague, who is also married. This happens intermittently. He never says in advance that he's going but always admits where he's been. Plus his phone always tells me where he is. Am I being paranoid? Last week he said he wanted to give me a lie in. Late evening (11.30 pm) she WhatsApp him to thank him for the walk.
