The Flags Of Our Father star married the Oscar-winner Witherspoon in 1999 and they have two children together - seven-year-old Ava and three-year-old Deacon - but they split in October (06) amidst rumors Phillipe's partying and flirting destroyed their relationship.

However, Phillipe insists the rumors are untrue, saying, "I'm not a perfect person. (But) I'm not guilty of a lot of things I have been accused of. My priority is and always has been the health and safety of my family."

Now, three months after his split from Reese Witherspoon, Ryan Phillippe says, "This is the most difficult time in my life."

"I must stay focused on my kids," Phillippe, 32, tells TV's Extra in an interview airing this week.

"I have not found balance in my life yet."

"It's unfortunate when you have kids ... but I signed up for this and have to deal with it. I don't read the magazines or watch the shows. ... It's hard when people follow me to my kid's school."
