Chicago White Sox pitcher Jace Fry’s engagement to his fiancée, Kelsi Blalock, may be on thin ice, at least that’s what many people assumed after Blalock attacked the baseball star on Instagram.

During Fry’s first career start Wednesday, Blalock posted several photos of the couple with captions that seem to accuse the pitcher of being unfaithful.

In one photo, the caption read: “26th birthday at the ballpark: wasting another year of my life on a sociopath.”

Blalock followed up with another claim, “We call this at the bowling ally he took the girl he was screwing with when I wasn’t in town.”

In several other posts, Blalock alleged Fry gave her an STD and gave his number to other women.

“When you think he won’t give you an STD again …,” Blalock also said.

“Give that girl over there my number, but don’t tell her I’m engaged,” Blalock said in another snap.

After deleting several of the original posts, Blalock followed up with a separate tweet, titled, “Explanation.”

“‘You speak so highly of him,’ he said to her, ‘Why do you do that? Why do you speak of him as if he put the stars in the sky when he did nothing but break you so god damn much that the cracks in your heart were practically visible through your eyes.’ She laughed, ‘that’s the thing about love, isn’t it? You’ll let them get away with murder, even if it’s your own,'” the message read.

Although their relationship seems rocky, Jace and Kelsi still have an active wedding page on The Knot.
