What does it mean that my boyfriend took a photo with his ex and said he didn't delete it? Ask for comments

Dear, it is the present and future men who accompany you all your life. Why should you care about the private affairs of the past? Too narrow-minded. Why don't you leave some privacy for your boyfriend? I believe that he will gradually forget and delete with your company. Give him time, and you are not allowed to mention these things in front of him to show a woman's generosity.
