The `Mr. Popper`s Penguins` actor - who split from girlfriend of five years Jenny McCarthy in 2010 - admitted after having had to "erase" a number of former flames from his life, he doesn`t know if he will ever commit to another person fully. He said: "I`ve been erased and I know what it`s like to erase someone. You know the feeling when you loved somebody and it ends and you feel as if they`ve moved on or maybe even none of it ever mattered? It`s a terrible feeling. "But everything in my life comes to me for a reason, to step me up to another level and to make me learn. Every single relationship has brought me a little bit closer to realising what I want and what I don`t want, and teaching me the value of love. "I don`t know if I`ll ever actually find somebody I can hang with for the rest of my life." The 49-year-old star - who has battled with depression in the past - explained he has on occasions veered into a "bad neighbourhood" in his life. Jim added to the Daily Telegraph newspaper: "I veer off the road once in a while and take the off-ramp into a bad neighbourhood and live there for a while, but it`s not usually very long. "Everything starts to go wrong and you can only stay in that mode for a short time if you`re awake and sober and looking at the universe."
