I guess my thought on that *for me* is that if my gut tells me I can't trust someone, either 1) my gut is wrong and I have trust issues and therefore no business being in a relationship; or 2) my gut is right and the person is not trustworthy and I shouldn't be in a relationship with them. With my STBX, it was #2. Right now, at the point of my life I am in, I am at #1 where I know I will have trust issues in any relationship and therefore I have no business being in one with anyone.
