We look for relationships to feel more complete. When we are alone, we usually feel like something is missing. The Masters have said that man is half a body and woman is half a body. Together we make a more complete human being.
A man only sees one thing at a time. A man will often see only one possibility and pursue it until it doesn’t work. Then the man will pick something else and pursue that until it works. Meanwhile the woman sees the man doing something and thinks why are they doing that when they should be doing this instead. The woman gets frustrated with the man for not seeing what she sees.
