In need of advice on facebook diliemia?

I ve been talking to this guy I like for about a month, I noticed that when he added me to his facebook page, he deleted alot of content.He deleted hugs that he sent to certain friends, which is through an facebook application, and a couple of girls comments who wished him a happy birthday, and he deleted smiley faces he sent to a couple of his friends via a facebook application.Plus,, he deleted everything going back a few months ago.He had me on a limited profile where I can only go back and see so much, but with my friends profile, you can see everything going back a few months ago, and theres nothing really incriminating, he did make a comment on some girls photo saying it was nice pic, and the other day we were both online, and he makes a few comments on some girls page,"He love her photo" and "Oh it that you on the right" on a three year old picture and how he went to vegas memorial day weekend, but nothing too bad..then he has me blocked from seeing his highlights,( the highlight sections is where you see the person add photos, or comment or another person photo, or any type of recent activity) he has it where I m not able to see it.. I know this because my co worker when he logs on, he can see his highlight section, I dont understand Why is he singling me out?
