history: Me and my girlfriend have been dating for 3 years now. Im going to ask her to marry me and I have no doubts she will say no. Im going to ask my girlfriend to marry me this weekend! I have no doubt in my mind she will say no
current: That is so exciting! Best of luck to you man! I doubt she would reject such a great guy like you. :) 
next: Thanks! I think we are doing well so i wont be disappointed or sidetracked by a no from her.
