1000-lb Sisters’ Tammy Slaton DUMPS ‘BBW King’ boyfriend Phillip as he said star was ‘insecure’

, Amy meets up with her older sibling for a workout and kicks off a conversation about Phillip, which leads Tammy to drop the bomb.

"We broke up," Tammy shares. "I guess you could say I did it, cause I was tired of fighting with him and he said my insecurities were my problem.

"And, like, at the beginning of the relationship I told him, I was like, can you promise you'll help me through my insecurities. He said it got to be too much."

Amy tries to look at the positive side of things and responds: "Him saying you're insecure and stuff, maybe that needs to be the motivation to be, like, getting your inner demons worked on."

"I got an inner demon?" Tammy asks, clearly confused.

"Yeah, your inner food addiction, and your insecurities," Amy says, as she urges Tammy to lose weight before her next visit to her bariatric surgeon, Dr. Eric Smith.

Amy, 34, explains: "Now with your Dr. Smith appointment coming up you've got to show some real progress, so you need to do this like, every day. Even when I'm not around."

Amy also shares her thoughts in a separate interview: "Tammy told me she broke up with Phil, and I'm like, about damn time.

"Now you need to work on yourself. Tammy don't need somebody that wants her to be a glutton."
