Anxious with Fiance – bbr

I was recently on a trip with my fiance and several tines I felt resentful towards her. I recognized it was my thoughts causing the feelings but I couldnt figure out the thoughts. Once I told her I was annoyed – shes an empath and can read emotions very well – I felt much better.

How do I figure out my thoughts in those situations? When I try to think back to the moment I get is the feeling.
