A bit of background... my brother was married for 18 or 19 years, and left his wife for a another woman. The woman in question is an ex-girlfriend from his younger days. I don't agree with what he did how he handled it, but there is nothing that I can do about that. He was very close to his daughter before he left. Somehow she managed to not know that anything was wrong with her parents marriage during the last years before he split, so I think it took her by surprise (she was 17 at the time). Even though before he left the daughter was closer to him than she was to her mother, she sided with her mother. With the way my brother acted, I can't blame her. The divorce was pretty ugly, and the ex took my brother to the cleaners (and did her best to turn the daughter against him). About a year after the divorce, the ex remarried. The daughter still refuses to meet the 'other woman' and is apparently upset that my brother married her (about 6 months after the mother remarried). My brother doesn't have a fb page, but his daughter does. She is 22 now, and accepted me as a friend though she won't talk to me so I think I am just a number to add to how many friends she has. I leave it as it is because at least I can see what she is up to. She has her privacy set so that you can't find her by name anymore. The thing is, she changed her last name on fb to her mothers new married last name. Some of her friends commented and she said that she 'finally got around to changing it', and 'it finally went through'. My brother is paying a large part of her college tuition, and every time the daughter needs anything they hit him up for more money. He makes a good salary, but since the divorce he is having trouble paying his own bills because of them. I have trouble feeling too sorry for him because of his behavior and the fact that he let his ex walk all over him during the divorce (all she had to do was tell him to 'think of his daughter' and he gave her what ever she wanted), but if there is a chance that the daughter legally changed her name, should he be told?
