Why dont you believe me? *vent*

When have I ever lied to you to make you not believe (almost) anything I say or is it you just think I'm so stupid that nothing i say can be true. I'm not stupid and I've never lied to you. You don't believe me until you hear the same thing from someone else, sometimes multiple people. Then you just give me a sarcastic condescending "you were right for once in your life, hahaha". Idk you still wont believe anything I say. What's your problem? I dont understand why we are still together. I love you but you dont believe anything I say even things like how long to bake chicken and honestly I dont trust your faithfulness. What kind of relationship is that? But your happy, our kids are happy, our families are happy..... I wont stay forever, everything has a breaking point and I'm about to leap out of this
