"The wedding planning has slowed down a bit," a source close to the Canadian heartthrob tells PEOPLE. "They still don't want a long engagement, but they are also not rushing the wedding."
Of the young couple's engagement, the source adds, "It was getting quite intense and they realized they want to enjoy being engaged for a while. It's not like they need to rush -- they are both so young."
"They aren't slowing things down though because they are unsure if they want to marry; they definitely want to get married," notes the source. "Justin and Hailey are great. They are very happy and having fun together."
Another source talks to Entertainment Tonight, "The couple have talked to a lot of people close to them, and are listening to the constant advice they’ve been receiving to 'enjoy the ride.' " The source goes on saying that the pair are "in a loving relationship and are working on the foundation now to maintain the forever."
The news arrives following a report that they were planning to go through pre-marital counseling to help them have a happy and healthy marriage. "Justin and Hailey take marriage very seriously, and intend to do it only once in their lives, so they have no intention of rushing into it," said another source. "They both want to attend pre-marriage counseling to make sure they are prepared for all emotional difficulties, and to learn the right relationship skills to see them through any tough times they may encounter in the future as a married couple."
"Justin and Hailey's approach to getting marriage is actually really adult-they'e going into this with their eyes wide open, as well as their hearts, and they are doing everything in their power to make sure it’s going to be a happy, healthy and never ending marriage," concluded the source.
