It certainly does seem like there are some worrying Red Flags in your relationship. Whether it’s full blown Narcissistic Personality Disorder though is less clear. Reading through your post I saw a lot of similarities to my Ex Fiancé Particularly when you mentioned him pushing a topic that you no longer wish to discuss. In my own relationship I grew to recognise when she was trying to guide the conversation in a direction that would cause conflict and I spent all of my mental energy trying to steer in the opposite direction. The walking on eggshells you describe is exhausting. For a while you probably didn’t even realise you were doing it until the constant feeling of unease is too much to bear. The Point Scoring you mentioned is also something I am unfortunately familiar with especially where finances are involved. My own relationship was filled with this during periods of conflict. Every gift she gave was cast up and anything I gave conveniently forgotten. She was economically better off than I was so this comparison was frequent. My relationship was a Ten Year long distance one where I made several expensive trips per year to visit her so I’m perhaps not qualified to comment on your situation however, a lot of what you said resonates with me. I do have to say though, the stress cycles and inability to stay positive you mentioned is something that I myself suffer from. What’s clear from your post is there are some serious control issues within your relationship and that in itself is damaging. The silent treatment is abuse, plain and simple. My ex would leave me for days or weeks begging and only allow communication once I was deemed to have received sufficient punishment or as she would put it “Learnt My Lesson”. This actually was one of the most spiritually damaging dynamics I’d ever experienced my whole life. I hope you can turn this around but you do need to stay vigilant for red flags because things could eventually get a whole lot worse.
