<human>: There's a lot of history behind these thoughts, but without getting into it I find after a relationship ends (I've had ~4, most are multiple years long), a fog lifts from my perception and I see every flaw so clearly, and I feel like I should have seen everything coming and should have ended things way sooner (or never even began).

It feels like I ignore, don't notice, or excuse *so* many things during a relationship that I should not be, but I can never see it until it's over.  This makes me feel like I can't trust the way I feel at all when a relationship is forming or during it.  And if I don't feel like I can see things clearly when I'm in the middle of them (and I don't, at all, not even a little bit)... I don't even know what to do.  How can I ever trust the way I feel, if I never see the picture clearly?

Give me the gist of the text in a nutshell
<bot>: Feel blind during relationships, which makes me feel like I can't trust my feelings, and I don't know what to do.
