Mine actually lasted 2 years, but it was a LDR so I think that suits some of them and also prolongs it. But wow in those 2 years, he was the perfect boyfriend! Adoring behaviour, cooked me all sorts of special foods he thought I might like for dinner, really well thought out cultural dates, he even changed his political views to match mine, although I never discussed politics - he just came out with it before the GE.
Interest gky, I'd known him for years before we got together and he was always extremely flirty with me, to the point that I couldn't understand why he didnt ask me out and got totally fed up with him. Turned out he had a secret girlfriend in a LDR!
The discard and mask dropping with him was sudden and shocking. He went from adoring and perfect boyfriend/saintly virtue signalling, highly moralistic, non rule breaker to cheating on me with the replacement he had lined up when he got bored during lockdown and dumping me in a 3 minute phone call. I got my belongings dumped on my doorstep and then every 2 weeks withiut fail, he blocked me successively on phone, WhatsApp and various social media sites. I got a few curt text messages saying things like "I think I'm just bad at relationships" and "I had to be honest" so that I changed his name on my phone to "Voice of Doom".
He was so overwrought silly and taking himself so seriously that his behaviour actually became quite funny in a black humour sort of way. I just stopped reacting at all because I lost all respect for him.
Even funnier though was that the very week in lockdown that I was dumped, another good looking man with a trust fund that was single at or near 40, whom I knew vaguely got in touch by adding me on FB and then love bombing me classic style. He had so many similar characteristics with the other one, it was a bit spooky, even down to the "McBusiness" which didn't make any money but enabled him to sound busy and meet lots of women. Many, many compliments, trying to turn the conversation sexual early on because he "found me irrisistable/attractive/CBA to remember the rest".
We met up for coffee. It was OK. More love bombing, but intermittent. I just couldn't work up much interest in him at all because the other narcissist was so much better at being fake! One morning I woke up, felt really bored and annoyed by him, defriended him on FB and blocked him on WhatsApp!
You have to laugh otherwise you'd cry.
