Wanting to spend some time alone, Kate Winslet has split from her boyfriend Louis Dowler.

The Titanic actress took the decision as she does not want to commit herself to any relationship at the moment, reported Daily Mail Online.

The 35-year-old star started seeing the model just after she split from her director husband, Sam Mendes, in March. Over the past four months, Winslet and Dowler were spotted together almost everywhere.

A close friend stated, Louis was just the tonic Kate needed after her painful split from Sam and they had a wonderful time.

However, they have realised their relationship isn't working and Kate needs space to be on her own. She is very grateful to Louis for helping her pick her life back up after her marriage ended and they had a lot of fun together, but she felt it had come to an end and wants to concentrate on her career and children.

Sources also revealed that Kate realized that the relationship was more a case of rebound and she needed to step back to take stock. However, at one time she had indicated that she may even consider marrying Louis Dowler and had even introduced him to her parents. The model reportedly got along well with her children too.
