The way for a loving and long lasting relationship is to be patient and really interested - willing to make the necessary effort. Don't get fooled by the other person's games (maybe she's just using the 'boyfriend thing' as an excuse?), be serious and intellingent. Don't compromise your beliefs and personality, but show that you turly care and that you can give her as much time as she needs.
Also, don't try to be a 'loving wimp' - I think few women like it when their partner shows too much of a feminine side. Stand by your beliefs. Good luck!
I don't understand what this person was trying to say. You don't tell a person that you love him/her the first day you meet him/her. But showing affection is essential for any feelings to develop. They do have to be appropriate, but they do have to be present. A flower, a little message, a little good morning over email... just watch the response of the other person. If she responds the same way, means that she reciprocates your feelings, if she doesn't - don't push. She might need more time to get used to this or sort things out for herself. Be appropriate in your love messages.
I've known many cases in which the girl didn't like the boy at first, but he proved over time that he's the best person she ever met and she madly fell in love with him - thanks to his patience, appropriate-ness, not being pushy, but giving her as much time and space as she needs, while making sure that she knows that she can count on him.
