Trust is perhaps the most fundamental pillar upon which a relationship is based. The stronger the trust is between two people, the stronger the relationship is. When a relationship suffers from a lack of trust, it means that two people have trouble believing in one another and having faith in their bond. As a result, there are always issues and fights in their relationship. They often wonder why things are this way. Here are a few reasons why he has trouble trusting you:

He secretly questions everything that they have heard from you.
