Brooo, how old are you?It takes 6-8 weeks for a criminal record/vetting process check to be completed.
Two weeks is too early to make such a monumental judgement.
It needs to be throughly investigated, i would even suggest go to extreme measures and do a bit of stalking to see what she gets up to, if she drives ? take her number plate down follow her like an undercover police officer for a few mins.
It will only benefit you in the future.
