My boyfriend's high school yearbooks...

My boyfriend won't let me look at his yearbooks because his ex girlfriend wrote all over them. I don't care about not reading what she wrote, but it does bother me that he has "love letters" in a sense in them.. I know that she filled up the hole page and everything and it just bothers me. I wouldn't want our kids to read the yearbooks ever. I'm just struggling with this and am not looking for judgment.
