Whenever the two of you are together;

Always try as much as possible to provide her with your undivided attention whenever you are with her.
Listen and show interest in whatever she is saying and try to support her views or takes on issues.
Now all of this will not be complete without showing or displaying to her the romantic affections that burns in your heart.
Never forget that diamonds are a girls best friends, please note am not telling you to buying her diamonds but what i am trying to pass across is that you should try as much as you can to always buy her thoughtful gifts. http://worldtalksnow.com/2016/06/05/win-heart-woman/
