A lot has happened to Lupe Samano Donovan since she was featured in an episode of "My 600-lb Life" in 2016. She is down to half her size, but she is still facing some difficulties including the threat of separation since her husband seems to be fed up with being her caregiver.

2 Paragraphs reports that when Lupe was first featured, she had so many health problems due to her weight that she was bedridden for almost 10 years. She did not like going out at all because of how heavy she was. She experienced an embarrassing moment when she got stuck at a booth at a diner, and the fire department had to be called in order for her to be assisted.

After appearing on the show, she underwent through a gastric bypass surge after which she lost half of her weight. But despite this improvement, Monsters and Critics reports that Lupe still does not want to go out in public. She claims that she does not have the strength to get out of bed despite being half her original size.

This struggle may be psychological in nature. An added factor maybe that Lupe is anxious about her relationship with her husband Gilbert. He has served as her caretaker for so long, and it may also be taking its toll on him.

Before the airing of the latest episode of "My 600-lb Life," he tweeted his followers to pray for him and Lupe as they are "going through it." He did not specify what it was they were going through, but some say that there might be trouble in the marriage.

Speculations indicate that he may be getting tired of the sacrifices he has had to do for his wife. Do you think that Lupe and Gilbert's marriage will survive? Share your thoughts on the latest "My 600-lb Life" episodes below.
