My husband is still friends with his college girlfriend. He’s known her much longer than we’ve been together. The other day, he left his phone on the counter.I glanced over and saw that he ended a text message with XOXO. This made me mad even though I don’t think the two of them would ever get together and have an affair. I told my sister what my husband did. She says it’s a form of cheating and disrespectful. When I scrolled up, I saw that he ended another text message with a kissing lips emoji. Is this cheating? Am I being oversensitive? Can emojis be cheating?
