Splitting up with someone is often very traumatic so I don’t think your behaviour is irrational. I sure don’t think you are crazy – you’re in pain. As things stand she doesn’t want any contact but that might change when things settle. Narcissist – no way. When I was in my early 20s I did something very similar and of course like you I really regretted it. I learnt a lot from it though and now (I’m nearly 50) understand why it was difficult for me to deal with my feelings at the time.
