Chelsea Houska has a new man.

After spending years living the single life and dealing with the drama surrounding her ex, Adam Lind, the Teen Mom 2 star says she’s finally in a healthy relationship.

“I’m seriously the happiest I’ve ever been,” Houska, 23, tells PEOPLE of her relationship with beau Cole DeBoer. “I mean, it’s just so good I couldn’t imagine not being with him.”

The couple have been dating nearly a year and are already starting to plan their future together. In fact, Houska revealed that she and DeBoer, 26, already have plans to move in together.

The relationship is a marked contrast to her previous one with Lind, who is the father of their 5-year-old daughter, Aubree.

Despite ongoing conflict with Lind, which viewers have seen play out on the show, Houska still plans for more babies – with DeBoer!

“The babies would be so cute,” joked Houska.
