Would other people jump to the conclusion that their partner cheated because they found lipgloss under a car seat? If I found panties in the car, yeah… I would take issue, but lipgloss could be from anyone at any time, including his own family. In his case, it could have come from TLC either intentionally or not. Gino’s new life with Jasmine is going to put him in an early grave. I can’t imagine being on this constant emotional roller coaster.
I would assume he leant the car to someone while he was out of the country and that person (or someone they had in the car) had left it. Then again, I’m not writing conflict storylines for reality tv.
