Kaitlyn Bristowe admitted she is still coming to grips with her ex-fiancé Jason Tartick moving on.

Shortly after Tartick went Instagram-official with his new girlfriend, Kat Stickler, on Wednesday, Bristowe shared her candid reaction in a private Facebook group.

“It’s actually hurting more than you know and for reasons other than most know,” the former “Bachelorette” wrote from her verified account, according to a screenshot seen by Page Six.

Bristowe, 38, asked the group’s other members not to “make assumptions” about her feelings, adding, “This is hard and that’s confusing for me too. Not just you.”

In another comment, the “Off the Vine” podcast host shared that she has “some held on anger and resentment” that she is “working through” but clarified she is “not hurt.”

She did not immediately respond to Page Six’s request for additional comment.

Bristowe’s response came mere hours after Tartick, 35, and Stickler, 29, shared a pair of cozy photos in a joint Instagram post, marking the first time they have confirmed their relationship online.

The new couple was first linked in April after attending a party in New York City together.

Tartick has since met Stickler’s 4-year-old daughter, Mary-Katherine, whom the social media influencer shares with her ex-husband, Mike Stickler.
