As Dedworth says, put it down to experience and move on. I'm sure you have feelings for this girl and it will be hard, but I guarantee it will be easier to do it today than it will in the future and will stop you suffering from more dissappointment and let downs in the future. I speak from experience of this, I was with my last Filipina g/f for 10 months, the warning signs were there after a month but I ignored them time and time again, thinking I could change her
There's no point being miserable in a relationship when there are lots of geniune girls out there who will do all they can to make you happy and keep in touch with you.
