I personally don't think this guy is going to give up that easily. This guy wants to "rescue" Emily from her sitch and try to make everything wonderful for her. Even IF Emily was divorced and liked this guy's personality, it would still be a bad relationship because it would be starting off on an unequal basis, because this guy doesn't think Emily can take care of herself without his help.
Emily, you need to get this guy out of your life. Don't worry too much about hurting his feelings. He has no right to try to impose himself on you, which is what he is doing.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
