It was somebody who seemed cool, and then at one point said, "Btw I've got kids, so I suppose you're gonna be put off by me now."
In honesty, I didn't want to date someone who had kids.
I said that thanks for letting me know and it wasn't what I was looking for sorry but it definitely wouldn't put people off and he shouldn't worry about that.
This seemed to infuriate him, he said, "Well thanks for your patronising response, and don't worry, I'm sure you'll have no trouble finding someone with your manly/boy looks!!"
I just blocked him, it was a lucky escape and said way more about him, there was no need to be so nasty.
I didn't mean to sound patronising, he just seemed certain that women wouldn't want to date someone with kids, but it's not true for everyone
