This is going to sound blunt, and cruel. But I mean it in a big brother kind of way.
Shut up and buy her some flowers. You love her. She loves you. So what if you had a fight? So what if you had some stress in your life? We all have stress and we all don't get along sometimes. Make up, get back together and take her out to dinner. You both mean a lot to each other and it's tearing everyone a part to see you two so seperate from each other. *shrugs* That's all I can really say.
