You will never be able to articulate to your partner how you come to the decision to lie. And just as important, you will never be able to justify it. If you can lie that much and so easily, then how can you also trust what anyone else says? It’s a never-ending cycle. RELATED: Why You Have Trust Issues And 5 Ways You Can Start Putting Your Faith In Others One of the most important things we look for in a relationship is security. We want to know that we’re coming home to someone who would never intentionally hurt us. Security in a relationship means knowing what to expect from your partner. If you lie, you remove any foundation for trust or security in the relationship. Trust is the biggest part of a relationship, if you don’t have trust, you don’t have a relationship. If you can lie about small things or make yourself look better when telling a story, then how is your partner gonna trust you when you tell them you’re somewhere and they’re secretly spending the whole time if you’re even where you say you are at all. Since your partner does not know where you draw the truth-telling line, he/she will never know what to expect from you in the relationship. Not knowing what to expect is the opposite of security. And when we’re insecure in a relationship, we get annoyed and jealous.

You don’t think it’s any big deal to tell such a small lie. You cut off the tags, throw away the receipt, and you think you’re safe. Then he overhears you telling a friend about your splurge, and all hell breaks loose. You can’t understand why he’s so angry; it was just $20. But he doesn’t care about the $20. He wants to know what else you’ve lied about. Surely it wasn’t just this one lie. And he has no idea what you’ll be lying about in the future. He’ll question everything you say. He’ll wonder if you’re cheating. You will never be able to articulate to your partner how you come to the decision to lie. If you want a happy relationship, just tell the truth!
