You don't need to argue with your emotions, or block them, though you would be wise to notice them and treat them as real. You seem ready to step out of a corner that you somehow let yourself get backed into, and the issue seems to be whether you really can trust someone. Looked at more closely, though, the question is whether you can trust yourself. If you can manage that much, you will be able to make more sense of the potentially erratic thinking and/or conduct of someone you're close to. I suggest you hold open plenty of space for them to go through their gyrations, and to express everything they want to express, including and especially their contradictions. As they do this, if you're paying attention, you will have all the information you need to figure out exactly what's going through their heart and soul. Just be aware this could take a little while. You may have reasons to change, radically shift, or end the relationship; I would urge patience and forbearance. Act like you have all the time in the world. While you're doing this, you're going to learn a lot and I do mean a lot about some inner questions and issues that you've been wondering about forever. The tolerance you offer to others is the same as what you offer yourself. The truth is organized in layers—therefore, patience really helps.
