I stumbled upon some WhatsApp messages on my Husband's phone. He was in BKK last weekend. The content to his friends was the recommendation of a dirty massage parlour in BKK where he said he "just goes for a shower". I know that this massage parlour is definitely a sleazy one (Google and message content says so). Our child is barely 4mths. He usually deletes his messages and I didn't manage to save them. How would anyone go about this?

"Stumbling" or checking your husband's messages is never a good idea. It may or may not open a can of worms that you can or can never get over. If I were you, I wouldn't directly confront him about the massage parlour because you reading his messages is also technically wrong and I can imagine the argument going round and round where no one wins. I would do the whole reverse psychology thing, asking him about his trip and also talk about how tired and alone I was when he was overseas and observe his reactions when I say that. But for the sake of answers, going to him directly might be the only way. Be prepared for an argument though. This kind of predicament is never easy.
