I have been seeing someone for almost a year now and last night his last message seemed a bit unusual. I sent a text to say good night and he responded with a number of emojis. He is very articulate and not usually big on these and they included an aubergine 🍆 which I found odd so I asked if he was talking to someone else pointing out that it was unusual. He has now taken offence and was very defensive. Was I BU to ask?
