Our relationship hasn't been great recently. He was sat in front of me and texting a mate. He kept turning his phone on an angle which piqued my interest. Anyway I couldn't properly see what was said but could definitely see my name. I asked what he was messaging about and was told TV. I told him I thought he was lying and he got shirty with me and moved alongside me so I couldn't see anymore and turned his phone on silent. Should I just leave this alone?
