In order for a long term relationship to work, both sides must feel all emotions in the spectrum, happiness, sadness, jealously bla bla bla........... There are many physiological reason for this, which I cant be bothered to go into. The keys is to have the correct balance of these emotions. Most people fail as the balance is fucked up, or one feels it and the other one doesn't, the emotional bond should be mutual between both parties.
