Really. He blocked OP and others that were previously his Friends. In case you're not familiar with FB, if he didn't make OP a Friend, she couldn't see anything about his profile anyway. So why block her? That's just hurtful.
Immature.
Yes but if one of their mutual friends comments on something of his, she can see it.If they post pics that he is in, she can see them. I'll be honest with you, I'm friends with my siblings on FB and sometimes wish I weren't, lol. I would not take it so personally, OP. I certainly would not let it destroy my relationship with my brother.
