Singer-actress Jennifer Lopez has been in failed relationships several times, but she admits she has learnt a lot from her blunders. She has had three failed marriages, a high-profile broken engagement and a recent split from Casper Smart. The 45-year-old is now trying her best to not repeat the mistakes, reports people.com. "Everybody has seen that I make mistakes. Each time it goes wrong it's hard," she said. "I get really hurt but I have to let myself go: 'What did I do? What can I learn?' And as hard and as hurtful as things get, I want to believe I will be able to go one step higher. I've got to hope that if I keep going I will eventually get it right," she added. Despite all her romantic woes, Lopez, who was recently linked to "Dancing with the Stars" pro Maksim Chmerkovskiy, has not given up her search for 'Mr. Right'. "I still believe in love. The nirvana man, he's out there somewhere. But you just have to work at it. You have to work at everything," she said. (Source: IANS)
