How to give my girlfriend emotional support?

My girlfriend and I were on a break for a month and that was the longest month ever. Just recently we started working things out with each other and she mentioned that she wants me to take control of things and take care of her emotionally. If anyone can help how do I take care of her emotionally? I really want this to work out with her because I love her so much I can’t picture my life without her. Please help..
