If you learn how to become an expert at meeting her needs, she won't have these thoughts that bother you. So much about marriage consists of self-reinforcing cycles that we fall into. They can either be positive or negative, the goal is to get them to spin the right way.
The classic example is sex and conversation. Women typically want to connect through conversation before they are willing to have sex. Men can have a hard time engaging in conversation when their sexual needs are not met. You are less likely to want to have a conversation, she is therefore less likely to want sex, which makes you less likely to want to talk and around you go.
That's just one example but there are many others. Learn how to identify them and be the one to go "first" to break the deadlocks. When you figure it out, its very empowering. Understanding the cycles that you fell victim to is something you can work on.
