When it comes to spirit guides, free will is a major factor. Spirit guides are there to work for you but they can never step in the way of your free will. This is why it's so important to be clear with them about what you want. And to be clear not only with your thoughts and words, but through your actions.
Since we live on a physical plane our physical actions count more than what we say or think. So for instance if you say you want a man that treats you well but keep accepting those that hurt you or stay with one that hurts you, your free will is telling your guides you really want someone that hurts you.
Then your guides see that and say “as you wish” and keep sending men that hurt you your way. So being sure your actions match what you truly want is super important.
Now when it comes to negative spirit guides most people see them as some evil entity but that's not the case. Negative guides aren't negative, we just hire them to do things that aren't helpful for us therefore they are negative by blocking us from our true self and holding us back.
So an example is someone goes through a hard time and hides from the world and completely isolates themselves. As they keep making the choice to do that with what their actions are saying, their soul then hires a spirit guide to help them to isolate.
Then this guide will block opportunities to get back to life and will help you to create situations, reasons, and excuses to keep that up and to keep isolating and it makes it harder to move forward.
So it happens when we make a negative choice to help us cope in that moment but keeping that choice up is what causes us to hire a negative spirit guide to help us to continue that.
It can show up in many ways but the key is to look at what your actions are telling your spirit guide that you want. Pretend it's a silent video and they can't hear your words at all. What are your actions telling your guides that you want? Are they congruent to what you really want?
And a negative choice for one person may be a positive choice for another. That's why it's important to make choices that align with your purpose gift and who you are at soul level. Everyone is unique.
So overall, really pay attention to what your actions are saying and make sure they match what you really want.
