New York, Aug 2 - After her much publicised break-up from American football player Tony Romo recently, American actress-singer Jessica Simpson is finding it hard to deal with her heartache, and so has decided to take a break from men.

Imdb.com reports, in the meanwhile, she is said to focus on self 'inner growth'.

'She needs time to clear her head, so she's putting dating on the back burner... Jess knows she is overly needy and tends to define herself by the men she's with,' said a source.

A close friend of Simpson said: 'She's refusing to be set up, she doesn't want to date, and she's definitely avoiding meaningless hookups. Jessica wants to figure out what she does to repel men and fix it... She's hoping that with a period of introspection, she'll be able to bounce back stronger and find her true Mr. Right.'
