are fantasies a relationship ruiner?

Fantasies in a relationship aren't really good, or are they?


I think it's harmful to have fantasies in a relationship and here is why:

• It's not good for you to get hooked into someone who's unavailable, and becoming emotionally invested causes you to react differently to your significant other.
• The fantasy makes you less emotionally available to other men/women.
• No one can ever measure up to a fantasy, it's not real. It's like the movies, that stuff doesn't really happen, although (I could argue that it has happened to me but that's a topic coming to you, soon.) I think it's best to stay grounded in reality instead, this way you don't have unrealistic expectations or disappointment when that person doesn't deliver what you expect. 

Good, Bad, Indifferent?
