Dude i reckon u r moving fast. You ve been here just for 2 yrs n u r dating a white gal. Good for you. You said when u propose her to marry you r confidently saying she will marry you. Marriage is a very big decision for Americans. They don't take it lightly. It costs money n time. Usually they like to date for at least 2 yrs n then get married. How long you ve been dating? She might be sleeping with u doesn't mean she really wants to marry you. Been there done that. Don't rush take your time. You know slow n steady wins the race. Never talk abt GC before marriage n even after marriage for sometimes. Play it cool, gud luck boy.
