There are always going to be missteps and miscommunications in relationships. However, when it feels like the arguments are constant or like you are ships passing in the night it might be time to seek an outside source. Lack of communication feels like not trusting your partner(s), like not knowing how to bring up the budget, or like not being able to talk about your sex life or parenting without there being conflict or disengagement. It feels lonely and isolating. Relationships should bring connection and intimacy, but it's not right now.
