So your dad ran off with his woman for an undisclosed amount of time and when he finally comes back after leaving you to fend for yourself for that period of time is an xbox? No offense, but if that is the case, he's not exactly a great parental figure.
But based on what you gave, there could be a lot more info that I am missing and could be completely wrong. So disregard if he made sure you were looked after by someone while he and his woman was away.
Also, Fable III finally got multiplayer right. it sucked in II but it was awesome this time around. I enjoy the game albeit being somewhat short on actual story line and the understone quest was really short for the price paid for it, so unless you're a huge fan, don't get the mission pack.
