RooSagicorn, is right. There must be something you are doing to them which hurts them.I don't know maybe you are not aware of it.
A Pisces will never remind you the wrong things you do to them. Instead, we react indirectly hoping the other person knows that they are doing us wrong. Hence we become cold and mean. I have similar placements, mars gem, Venus Pisces, moon Leo, sun Pisces in the 10 house.I am usually moody, especially in the morning. I remember, one day my girlfriend came to my house in the morning asking me questions and I reacted by being sarcastic. She told me that I usually act this way most times.
Sometimes, we don't know it but you have to remember that Pisces has two personalities. Just like Gemini with the two twins, we also have two fish swimming in opposite directions. Which symbolises negative and positive personalities. But we are much better than Gemini when it comes to personalities because we are sensitive.
So your Pisces might be swimming in opposite direction because they noticed that there is something they are not comfortable with you.
