Pick a card readings are linked to a whole number of people, not just you. With a pick of card reading, take what feels like the information you had to hear. If meditation helps you, than meditate on the reading to see how it fits in your life. You must also remember when you are getting a card reading, you are changing your own future just by knowing the information.
If you have been putting it to use, than maybe this is where the change had started from. If things have gotten bad and depressing about the relationship you wanted to be in. Than maybe ground yourself and see the bigger picture, or ask yourself if this is where you wanted to be. If you had ask for signs, than take what feels like is a sign for you.
This sudden bad spin might also be a sign in itself, maybe the relationship isn't the one. So the deities might be trying to tell you so. Take what resonate with you, in order to find the turth.
