The couple announced the end of their seven-year marriage last month, but the Latino star is said to be already finding life hard without the mother of his kids, twins Max and Emme.
A source told Us Weekly, 'His mood shifts from blaming her to begging her to take him back to telling her she is destroying his life.'
And when it comes to hashing out a divorce deal? 'He's being difficult on every little point... He wants to prolong things so she reconsiders,' said the insider.
Meanwhile, J-Lo is said to be loving life as a free, single lady, and has no intention of going back to the marriage.
'She is very happy,' said a third source. 'She is surrounded by love.'
