So my girlfriend (shes 28, im 22) of a few months now told me she might be moving in with a guy 'friend'. I dont know much about this guy, but to me this just sounds like trouble. I dont for a second believe that this guy would just so happen to be a white knight. Also, I dont know if i trust her, even though she's incredibly honest about everything (she admitted that she had cheated before-- according to her it was a bad relationship in which he didnt want to change, so she broke it off the next day, and started seeing the guy she cheated with-- her last ex of 3 years). I like this girl, we get along great but i couldn't cope with always having to worry and having her in the back of my mind! So Ive got a bit of a conundrum on my hands here, i need advice. What do i do?
