OTMT, This is where you stay strong. You stand up as a man and tell her you love her and are for the marriage. You are not giving up on "us". You state it with conviction over and over. If you have fear or hesitation or doubt- you do not show that to her.
I can think of a few scenarios- she is incredibly hurt, or feels incredibly hopeless, or feels that she has no choice, or it's a test to see if you show how much you do care for her, or she feels justified in making you suffer some since you have made her suffer.
Regardless, you have to take a solid, strong stance. Women want to love their man, they do. If you stand strong for a long time- I think she will choose to stay with you.
Or, your alternative? Just give up and wonder... wonder what if you had taken a stand. What if you had persisted despite doubts and fears. Courage is defined by how we act in the face of fear and doubt. Have the courage to face this battle.
You are strong- you can do this. You will not regret doing it.
