Yes well the only thing you can trust is that they will be unpredictable.. and that means accepting the yin and yang of their mental instability. lol

As others have mentioned, do you mean spontaneity or temperament? If you're someone who likes to try new things or have adventures on the fly, that's one thing. But if your emotions are all over the map and you can't discern when and where it's appropriate to say or do certain things, that can be a red flag. Just my take on it. There are people who don't like spontaneity and like to be controlling regardless, so if that's the issue and you just like to be more adventurous, I'd stay away from someone who doesn't appreciate that.

Unpredictability does not nesicaraly mean untrustworthy. When I hear unpredictable, I hear someone who goes on random adventures or gets a tattoo or brings home a random animal. It is possible to be random and spontanious and still reapect the person you are with. If someone takes the time to get to know the person, than you can see where their priorities are and wether or not they are trustworthy. Its the same as any other person.

I wouldn't necessarily name yourself like that, especially as unpredictable, just because people can't read you. My cousins answer to you would be "it's hard being a butterfly". We don't always know what we want, but I think it makes us unique and never boring!

If being unpredictable means you do what you damn well please without regard of what it may do to other people, then NO.

I have a friend now that is very unpredictable and l do trust her. Possible yes. Rare probably.

You can trust them to be unpredictable! It's whether you can cope with that type of personality that's important. I quite like people who are spontaneous (better word for it) it makes them more interesting!

Like others have stated, you have to define and give us examples of what you mean by unpredictable. I can't give you a meaningful answer otherwise.

Yes. No. Yes. No.
