The songstress, 37, who announced the split in an emotional April 21 Instagram post, confessed on a recent episode of her "Whine Down" podcast that she has "a lot of resentment" toward the ex-hockey pro, 34, who sought treatment for sex addiction in 2016 after he admitted to cheating on her with multiple women.
"She's in a world of pain over Mike. It's because of his behavior that she doesn't trust guys farther than she can throw," shares a source, who says the heartbroken beauty "has been pouring all her love" on the couple's children, Jolie, 5, and Jace, 2.
"She's had a lot of lonely nights, and a part of her doesn't think she'll ever find a good guy," the source adds. "But her friends think it's just the grief talking, and they're optimistic she'll heal soon." Hopefully it won't be long until she changes her tune.
The couple split and reconciled several times. "Jana's exhausted from a whirlwind of emotions," says the source.

The money that Kramer is ordered to pay her ex would serve as a "full and final settlement of any and all claims," setting her free from any other financial obligations she might legally have regarding her past marriage with Caussin.
There are some things more important than money. As OK! previously reported, court documents obtained by Us Weekly revealed that the crooner is the "primary residential parent'' of their children, while Caussin is entitled to custody of the kids 125 days a year. The ex-couple also agreed to divide holidays to fit their individual schedules.
