Boyfriend is a Pisces man. We have known each other for more than half a year and are going to get married. But I always feel that he is still seeing other women. I wonder if it's my fault.

Since you can get married, it means that you have a love foundation and must trust each other. Your feeling is marriage phobia. It's okay. If you love him, you should trust him, tolerate him and check your wallet and phone records. It's really not a good idea, and it will disgust him. You should treat him with your heart and let him feel your tenderness and love. Bless you, my friend.
