Remember when you where courting and when the relationship was still in its infancy, when you used to buy flowers and small romantic gifts, and the little things which you used to do that where so special. Didn't that put a smile on your partners face ? I am sure it did. The things you use to do together that used to make you both smile and feel relaxed, like going for walks and going shopping together and holding hands in public. You really need to start doing those things again.
Cast your mind back to when you where happy with each other and when you used to have that belly laugh think back to the good things which you did then and start doing them again.
Its not too late to bring the romance back into you life. Don't procrastinate do them now.
