Intuition- A thing that one knows or considers likely from instinctive feeling rather than conscious reasoning.
When it comes to relationships, I beleive intuition is very significant and should be taken into consideration. Our intuition can provide a good or bad feeling about something or someone.
Often times in a situation where our intuition is giving us a sense of caution/alarm we ignore this and think things will be different or that we can change the situation. The result unfortunately is usually pain and disappointment.
A suggestion would be to sit in a quiet place/space and hear what it is your intuition is really telling you...it may not provide the answer you want but may be just what you need.
"Intuition is seeing with the soul."
