Looking at my boyfriend's short message, I found a short message about two years ago. The sender is a girl he chased before, and he never caught up with her. Should I trust him?

If you really care about him, don't always chase after his past. What you want is his future, why care about his past? Who can live without the past? He can always keep the previous information, which shows that he is an emotional person. Maybe he just thinks it's a regret in his life, but it doesn't prove that he still thinks about that girl. People are actually strange. They used to pursue a person desperately. It may be many years before you realize how stupid you were. Maybe you just have a crush. You are what he wants most until you meet, so if you love him and don't care about his past, please trust him. Please let both parties keep a little privacy.
