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.

for her Mom and me too actually. I think that my sister must have said something about what was on it. Both of us....gone. My sister also said something to her son, who is serving in Iraq, about something he said and that she was offended by. He edited it but he has not spoken to her since. Better for her if she had just ignored it but she is not wired that way.
