Selena Gomez has asked Justin Bieber to enroll in anger management classes in order for them to officially get back together, a source recently revealed, leaving many fans wondering if they may have broken up in the past over any form of domestic abuse.

However, Justin Bieber has never been formally accused of physically or mentally abusing his on-again off-again girlfriend.

"Selena has told him 'no romance without new manners', and insisted that he should take a course in anger management," a source told Yahoo OMG!

"Selena is an old fashioned southern girl from Texas and believes in manners and good behaviour. She's told Justin that he has to mend his ways if they are to start seeing each other regularly again."

Selena Gomez is worried sick about Justin Bieber after his police raid and it is reportedly affecting her lupus, HollywoodLife.com reports, leaving many fans wondering if they will slow down their relationship.

"Selena has been told repeatedly to avoid stress at all costs when it comes to her overall health," a source told the website.

"Lupus is triggered by stress and anxiety, and right now Selena is completely stressed about Justin and this whole egging nightmare. She's worried sick about him, but at the same time won't leave him. She's basically picking Justin over her own wellbeing."

Selena Gomez has not mentioned or posted about her on-again off-again boyfriend Justin Bieber since their last break up.

A source told E! News earlier this week that the couple is not back together.

The source also told the site that they did not recently vacation together.

"Selena and Justin have not gone on any trips together," the source said, according to the site.

"They have not left town together."

Selena Gomez has not posted any photos of her rumored vacation with Justin Bieber's family on her Instagram account , leaving many fans wondering if the "Heartbreaker" singer is trying to make up for previous relationship mistakes.
