I know I'm being lied to. The issue is a sensitive one, the situation quite strange and even a little frightening now that I am standing on the edge of the truth, which someone has offered to give to me in order to put me at ease, but I am not certain knowing the truth now will do anything but increase my already all-consuming anxiety. See, I believe the person with the truth is the person behind what he says he knows about. I have a strange piece of evidence to support this idea, and I think that perhaps whatever he tells me is his attempt to shift the blame from him and to another whom I don't know of yet, as he hasn't told me who he "knows" has done what has been done.

Should I trust this person, and hear him out on the truth he says he has?
Should I tell him afterward about how I think it is him?
Should I tell him straight away that I believe it was him, then hear him out?
Should I tell him I believe it was him, and that I don't need to hear his "truth"?

I thank you for your advice, dear being. Who would've thought that you of all the people here would attempt to help a fellow fucked-up soul? How very lovely of you. Thank you for your time.

Believe in yourself. Dig deep down for your self-esteem, take control of your life, empower yourself - and move on.
