Sandra Bullock will not be taking former husband Jesse James back despite signing-off on his decision to leave Los Angeles and follow her to Texas.

"She has absolutely no intention of getting back together with Jesse, ever," a source close to Bullock told RadarOnline in a Monday report.

Jesse recently received a judge's approval to take his 6-year-old daughter Sunny, whom he had with troubled second ex-wife Janine Lindemulder, to Austin with him -- which the source claims is the only reason Bullock doesn't have an issue with James' decision to follow her lead and relocate to Texas.

"The only reason that Sandy gave the green light to Jesse move to Austin was because she wants to maintain a relationship with his children.  Sandy loves those children," the source said of Bullock's feelings for Sunny and James' two older children with first ex-wife Karla James.

"Sandy is civil to Jesse for the sake of the children, that is it. If there were no children, Sandy would have nothing to do with him, period. And he knows that."

"She wanted the divorce done quickly, so that she could move on with her life."

James and Bullock finalized their divorce in June -- only three months after James was first accused of carrying out an 11-month affair with tattoo model Michelle "Bombshell" McGee while Bullock was in Atlanta filming The Blind Side, for which she won the Oscar for Best Actress.

Several additional women then also made similar claims and James admitted to the infidelity -- resulting in Bullock filing for divorce in April.

James subsequently stated it would be "selfish" of him to deny Bullock a divorce due to the "pain and devastation" his infidelity caused her but is reportedly hoping Bullock will take him back at some point.

"He believes that Sandra will take him back in time and that they just have to stay apart for a while for the sake of her public image," a source close to Lindemulder told RadarOnline last month.

Lindemulder -- a former porn star and recovering addict who was recently released from a federal halfway house for violating her parole on a prior tax-evasion conviction -- also plans to relocate to Austin.

"I'll move!  I'll move!  I can't get attached and let her go!" she said after an Orange County judge announced his July 20 ruling that James could take Sunny to Texas in time for the start of the new school year next month, according to People.
