It's not clear whether he's oblivious to the calls or purposefully ignoring them, but one thing's for sure: Amanda is worried Kyle is going to cheat on her again.
"This is so f--king f--ked," Amanda mutters in the preview just before the Summer House cameras flash to Kyle taking shots during a rowdy night out. "Drives me f--king crazy."
Things escalate from there, and soon, Amanda is gathering all of Kyle's luggage—not including the stuff she's already broken in the bathroom—to throw outside. Thankfully, Paige DeSorbo and Ciara Miller hear the commotion and swoop in to comfort her.
"I can't get ahold of Kyle," Amanda says through tears.
"But do you think he's doing something?" Ciara asks, to which Amanda responds, "My biggest fear was that he would get so drunk one night, he would cheat on me and he wouldn't even know that it happened. And then that's what happened."
The incident in question came to light during the Summer House season three premiere in 2019.
"I was completely black out drunk," Kyle said at the time. "I didn't even know I had it in me to cheat on you."
Promising to not "f--k up again," Kyle eventually earned Amanda's forgiveness.
However, as the sneak peek shows, she still has a difficult time trusting him. As she tells Paige and Ciara in the clip, "And now every time he gets this f--ked up, it's like just so triggering for me."
