<human>: Summarize the given text in a few sentences.

We've been going out for 2 years, she cheated early in the relationship and I chose to forgive and move on, she's since put herself in compromising situations with other men a few times since, eg flirting with friends, giving her number out to lads at work. In short my trust for her is pretty low but we're working on it with relationship counselling. 

This week she was offered a sketchy sounding job from a guy she met whilst selling things at a market stall. He wants to pay her £100 to go and work with him for a week at a market 100 miles away, and stop in his caravan with him for the week. 

I objected,  said clearly that I wasn't comfortable with it and wouldn't be happy if she went,  not to mention that it's dodgy as fuck. She argued with me and eventually just decided to go. 

I've called her and basically said I'm moving out and it's over.  Overreacting? Just need some outside perspective.
<bot>: dumped girlfriend as she decided to go and spend a week living in a caravan with a guy she doesn't know. Overreaction or right call?
