@NoDatingForOldMen I really appreciate that alternative perspective. All of our exchanges had been very warm and friendly up to the "if you are" reply last night. I was clear with him (despite my earlier private misgivings) that I was looking forward to meeting him.
For further context, he then went from suggesting that he'd like to come straight over last night after work, I replied that I wasn't looking for just hook ups, he said that he wasn't like other men, I joked "that's what they all say!". A well known line. I wasn't hurling insults or looking to offend, I was just teasing.
I was expecting a response along the lines of "well I'll just have to prove you wrong won't I winky emoji the coffees are on you tomorrow etc etc " or something cheeky about me in response. I certainly didn't expect him to react in such an extreme way. He clearly wasn't able to articulate why this offended him, or interested in explaining why. But then he'd never click with my sense of humour, and I'd end up walking on egg shells, afraid of offending him if he really took this to heart. The instant block based on one remark seems a bit extreme without allowing me a chance to explain, impulsive and immature. Like a child storming off in a huff instead of talking things through.
Anyway, I'm overanalysing this. I really appreciate the alternative point of view which is the value of this thread. I can be quite blunt and this has made me consider how I should tone that down before actually meeting people, for fear of being misconstrued. A lot can get lost in just messaging without verbal and visual cues.
I'm glad I didn't meet him this morning now.
