Your attention is what is worth more. Be caring and sincere. Don’t forget to text her even if it is a busy day for you. Do little romantic gestures like leaving her a cute note or making her some coffee. Cook for her. Surely your girl is the prettiest and smartest one but somehow women need to be constantly reassured of this so don’t forget to give her complements daily. Get her flowers when you can, they should not be fancy. Lastly, the ability to be interesting, to keep up any conversation and to have make her laugh is what is appreciated the most.
