Yes! So many people claim, “Well I met their representative at the beginning.” and to that I usually say, “No you met them, but you EXCUSED things or said ‘oh that’s just quirky. I can learn to love that.”
How do I know the signs were always there?
Because others usually see it and say something but the person does not listen to the warnings even from those closest to them.
It doesn’t mean the person is “bad,” but they might just not be a good fit into your world.
