An outright lie, no. Hiding stuff, perhaps. And being a mess myself and sometimes not figuring out what I actually want/mean until later, that too. I'm not easy.
Generally speaking, yes. I used to, always. I've learned over the past few years that people believe what they want to believe, and there is no point in trying to explain / deny / whatever. So, with some people, I'm just beyond truth. If you don't believe my word, then so be it.
