It is very difficult to revive the relations, especially if they were destroyed on your fault. Of course, there is nothing impossible, however if they were upset once then already something not as it should be. There is no harm in trying. But, if you love, then game is worth the candle.
1. Before making some active actions, be defined why you do it. Perhaps, in you plays feeling of the owner or that it is even worse - just a habit. In that case do not torment either yourself, or the girl. Release her.
2. If you understand that you are madly in love with the ladylove and cannot live without her, you should think over the gap reason. As soon as you clear it, try to talk on this subject to any familiar girl. Such conversation has pluses: you will be able to take a detached view of a situation and also to listen to the female point of view which, perhaps, to you will help to be defined with further actions. If you are guilty of a gap, said rude words and unpleasant things, dumped the girlfriend, she will hardly return to you. At least, there has to pass time that emotions died away, and there passed the offense. Perhaps, she will forgive you and will cause on a conversation.
3. You should start everything anew. You capitulated, the territory was freed. Win a part of its free time - write unostentatious SMS messages in which there will be no word about your last novel. Talk on abstract subjects. Let she will have a rest from the emotions overflowing it.
4. Become for it the friend. Evening walks, visits of cinema, the help with the house - all this you have to do absolutely disinterestedly, without hinting on any rewards in the form of a kiss or sex. The girl has to learn to trust you.
5. You have a mass of advantages before your rivals. You know this girl, her tastes, preferences, habits. Use it.
6. Be improved. Change. No, nobody speaks about cardinal changes, but if you found for it not enough time, were cold or stale, open before it the heart. Let she will see and will understand that it is only protective reaction from external influences, fear to seem too weak and helpless.
7. Women love strong men. Try to obtain it, despite of everything. Be her knight in the sparkling armor. Only time is necessary - besiege fortress, and one day it will fall to your legs. Girls are pleasant fine gestures and acts, do not stint gifts and attention, think out original ways of carrying out free time. Do a small holiday of every day of her life.
