What do you think about me telling my boyfriend I'm going to marry him?
Is there a reason you told him that?
It's the least thing I can do for him
I'm so glad for you! It's always great to be able to be open with how you feel towards you significant other. Congratulations on marrying the person you love!
I'm lucky!
Yes, you are lucky to find someone you love and want to spend the rest of your life with. Not everyone is so fortunate.
