The 'Radar' singer was recently rumoured to have been dumped by Trawick for pressuring him to marry her.
A source told People: "Jason did not break up with Britney. That's totally false. Things are casual… Britney really listens to what he has to say. He's been with her a long time, he gets along with the family.
"He has her best interests at heart, and he cares about her."
The insider added: "Things are fine - they still maintain a great working relationship and he's in her life as a great friend as he's always been."
The pair have reportedly been dating for the past five months, while the relationship has met with Spears's father Jamie's approval.
