Blocking a narc - help

[throaway292]

I have been dealing with someone who I believe is a narcissist. Our chats were flirty at first with some sexting and then I found out a few things that I wasn't happy with - such as he has a gf (100% does), which he still denies.

I have difficulty establishing boundaries so I said I don't think it was a good idea to continue communication and blocked him. I felt anxious the whole time and unblocked him, no bloody idea why, I wanted to make sure he was ok.

He went off on a rant and rave about how I've lead him on, I've treated him like a piece of meat, I can't just pick and choose when I want to deal with him and he doesn't know "who hurt me in the past to make me think this was ok". I apologised and said I won't contact him again, and have blocked him (for good!. But, the way he spoke to me, I feel so bloody guilty.

I am now worried there might be blowback as he said he feels I've lead him on and his tone was very strong.

Do you suffer from anxiety and worry in general or is this just now with this?

@JibbaJab I've always been a worrier and overthinker! I have had some relationships in the past where I had an ex who would make account after account to contact me when I blocked them (this was in my teenage years)
I also had an ex who would threaten suicide when I broke up with him and it was very traumatising to me - so I think when I reject someone, I either assume A) they won't leave me alone or B) they'll do something to harm themselves.

There was a time in my life I was very assertive. I feel like all my worries about this would just be diminished if I knew 100% he had a girlfriend because why bother. I've seen endless proof but him denying it to the level he did just makes me think maybe it's more complicated than I thought.

That's understandable, shame you had that experience it's not nice to have that thought burdened on you. In reality I doubt there is many that would act on that threat.

Regardless of the situation with the girlfriend, you already know he's not good news from his reaction and your reaction.
