"This time around, Justin is behaving like a gentlemen and showing how much he cares about her. He's is a lot more open about his feelings towards Selena, which has been a big sign of him maturing," a source told E! News exclusively.
The source said that Bieber is now better at keeping in touch, adding, "They've both been busy traveling but they do a good job keeping in touch when they are away from each other. Selena and Justin text all day and even FaceTime from time to time."
"They are still together and speak all the time when they are not together," a second source said.
Bieber "wears his emotions on his sleeve and whats to make this work," the second source told E! News.
"Everything is better with Selena and her mother," the second source told E! News. "A small percentage of it had to do with Justin but there were other issues they had to work on."
In December, another insider signaled to E! News that Gomez's relationship with her mom, Mandy Teefey, was strained long before Bieber re-entered her life.
Teefey said in January that she is "not happy" about her daughter's renewed romance with Bieber but is not interfering in her daughter's life.
"Justin and his mom are very close and he enjoyed spending some quality time with her. His mom keeps him grounded and humble, which he needs," the first source told E! News.
Bieber's mom Pattie Mallette, by the way, loves Gomez.
In 2014, the year Bieber and Gomez split, the former singer underwent much legal turmoil, which included a DUI arrest.
Nowadays, he's in a better place.
