Not to be disappointed in a man, do not let him in debt and do not make expensive gifts. Many of them say that if they ask for a woman in debt - so they do not see it as a partner. So that any consumer sentiment should be a signal to you that the question of trust this man to even consider not worth it.
If the situation does not fall under the above criteria, then this person has a chance. Just let it show itself. A good man will appreciate the trust and will try to meet your expectations. Easy distrust on the part of women often it whet he tries to do everything to make him believe, if you are dear to him. Another thing, if you basically put excessive demands, and can give a little - then he will not even try.
Tune in to the fact that much will you give selflessly, not counting at each instant benefit. Woman, internally rich can generously share their emotions and desires, without losing much (of course, it's not about sexual relations). Men instinctively feel when the fair sex are ready to share with them their happiness, and do not expect this from them. Work on your outlook and achieve inner harmony.
Try to become inwardly rich, and then the men will drive you around the dance. You will give and not to look back - and you will become much easier to trust. The problem of lack of confidence in the person associated with the collapse of hopes and ideals. Did you feel cheated when you expect from a person that can not give it yourself.
Try to meet with one that does not look like all your ex. Do not be afraid of new typecasting for business and personal relationships, and you will create a database of men worthy of trust. And you will be easier to trust them in principle, if you will have more positive experience - not necessarily intimate relationship.
