Trust is so important to happy relationships because it's basically impossible to be truly happy with your partner if you don't have it. Consider the following: Without trust, you'll have reason to worry whenever your husband isn't around. Is he doing what he says he is or has he lied to you? Without trust, you can't be 100% sure that your husband is committed to you. Is he in this relationship for the long haul or is he just waiting until something better comes along? Without trust, you can't be positive that your husband will do his best to respect and care for you. Will he embarrass or demean you in front of other people? Communication is key for trust to develop in a relationship. You must be open about your feelings. If there's something that your husband is doing to shake your trust, tell him! He can't read your mind, so if you want him to make changes, you'll need to talk to him. Try to voice your concerns in a non-accusatory way. You don't want to put your husband on the defensive if you don't have to. Try taking an open, friendly tone. For example, you might open by saying, "Hey, I was wondering if we could talk about us for a few minutes." As you make your points, say how his actions make you feel rather than criticizing him personally. You don't just have to communicate only negative things to him feel free to open up about how great he makes you feel as well. Good communication is a two-way street. Listen to what your husband has to say and try your best to understand him. You don't always have to agree with him, but he does deserve your attention and respect, especially when you're discussing difficult topics. It's also important to show your husband that you're listening. Maintain good eye contact and nod your head every once in a while. Occasionally, repeat back a point he's just made. Let the new trust in your relationship begin with you. A basic way to establish trust is to give him plenty of personal privacy (and expect that he gives you the same). This means not looking through his phone, mail, email or social media accounts. It also means not constantly calling him when he's out to see what he's doing or demanding explanations of what he's done. These kinds of actions feed your own insecurity and won't do anything to change what he is doing. However, this doesn't mean that you should turn a blind eye to evidence of bad behavior. Obvious warning signs mysterious texts that cause him to cancel your dinner plans with no explanation, for instance warrant investigation. It's important to lay down reasonable expectations for each spouse as early in the relationship as possible. This way, if someone behaves badly, you can clearly point out exactly how your trust has been betrayed. This is especially important if your expectations of your partner differ significantly from the "norm" (i.e., he should not cheat on you, flirt with other people, and so on). It is crucial if you have shared responsibilities (like child care). If you haven't already, have an honest discussion with your partner that outlines your expectations for each other. Be prepared to speak up about things in your relationship that aren't working, but make the conversation about what you feel, rather than what you suspect he is doing. For example, you might say, "When you're always late home, I feel as though I'm not important to you." Approaching it this way gives him the opportunity to see how you're affected without being accused, which may lead to confrontation.

Summary:
Understand the importance of trust. Talk to him about your concerns. Listen to him. Respect his privacy. Be open about your expectations.
