“This is something that every couple should do. That’s the whole point of a relationship — we are a family,” Asghari toldETwhen asked if he has plans to pop the question.

It’s been over two years since the pair were first romantically linked after meeting on theset of Spears’ “Slumber Party” music video.

Asghari also shared that he has an “absolutely amazing” relationship with her sonsSean Preston, 13, andJayden James, 12, Federline.

“What happened with Jamie and Sean was very unfortunate and definitely not right,” said the source, who added that their alleged fight on Aug. 24 began after Sean “locked himself in a room” after his grandfather asked him to do something “he wasn’t interested in doing.”

Jamie, 67, “got very angry,” andaccording toThe Blast, then broke down the door. “There was physical contact that made Sean scared and upset,” says the source. “Britney got upset as well and ended their visit with Jamie.”

The singer — who now shares custody of her kids withex-husband Kevin Federline— “can’t believe that her dad would jeopardize her relationship with her boys,” added the source.

“Britney is always terrified that she will lose custody.”

A rep and a lawyer for Spears did not immediately respond to a request for comment from PEOPLE. Jamie also did not respond to calls for comment.

The day after the alleged altercation, Federline, 41, filed a police report at the Ventura County Sheriff’s station with his lawyer Mark Vincent Kaplan. “Kevin got extremely angry when he heard what happened,” says the source. “His reaction does seem appropriate.”

According to Kaplan’s testimony as recorded in the police report, Spears’ 12-year-old son Jayden was also present during Jamie and Sean’s fight.

“Britney did the right thing and removed the children and took them out of there,” Kaplan previously told PEOPLE, adding that Federline still wants his sons to have “continuing and meaningful contact with their mother.”

Kaplan confirmed to PEOPLE earlier on Tuesday that Spears and Federline came to a new child custody arrangement last week which gives Spears 10 percent of custodial rights and Federline 90 percent. Kaplan tells PEOPLE Spears’ visits are required to be supervised.
