I don’t know if he is a psychopath necessarily. Just not a good partner and not an honorable person.

You were vulnerable when you’ve met him. That’s a sure way to meet a user. I had a bad feeling about this man after you had just one date with him, it wasn’t going to end well and it didn’t.

Well I had a strange feeling on the first date with someone myself and yet I stayed for years. And left for exact same thing I had an uneasy feeling on the first date about! Amazing. Whatever seems off in the beginning will be off 10 years from then and will likely be the reason for it to end. But hindsight is always 20/20.

It doesn’t matter if he is psychopath or narcissist. Be done with him. Just make sure you do not go even on one date with anyone for significant amount of time. We all make this mistake being lonely hurt and vulnerable after a break up and immediately going for someone else and that’s when trouble comes, always.

Don’t worry about why he is how he is. Just think about what’s next.

To answer how you spot a psychopath, I think psychopath is pretty extreme case and you would see that.

But other than that I think it’s important to pay attention to what they do, not what they say. And it’s important to get to know them on a deep level before committing in any shape or form, not focusing on things they say or how they express their undying love (fake).

Pay attention to their character and where they are in life and things they do and how they proceed in a relationship. He was very shady and not very trustworthy from the day one. It is what it is. I’d say you got out of this mess fast. Good for you. Others stick around for life in this mess. Be proud of figuring it out fast
