Trust is the foundation on which all relationships are built, it also forms the principle for healthy marriage life. If you and your spouse do not fully trust each other, the foundations of your marriage will begin to crumble little by little, which is likely to lead to major problems in the future. Trust is central to any marriage, and when you feel you can improve trust between you and your spouse, the time has come for you to take action. If you don't know how to increase trust, you may need to consider working with a counselor to improve your marriage. If you have friends who have been successful in marriage, you should never take pride in contacting them and asking for help. They can help you by providing advice that will guide you in the right direction. Sometimes it feels humble to ask others for help or advice, but why not do your best for a successful marriage?
