If you want the drama and your girlfriend to steal your shit and take it to cash converters, then by all means root it.
However you ain't into drama, and you are healthy and you have a good life, you might be lonely but its not worth the company just to fuck everything else up you hold dear.
How old is she anyway, I doubt she is a spring chicken and if she hasn't figured out her shit by now, she never will.
I don't like the text she sent you, she's a shit stirrer. There is a difference between wanting to start shit and wanting attention.
And would you bring her home to your mum, if no then run, run a mile........
