# Romantic love --this lover thinks constantly about the loved one, is jealous, unrealistic, will tolerate anything, is sexually attracted by physical appearance, needs repeated reassurance he/she is loved in return. Typically lasts a few months or a few years (some anthropologists say it lasts 4 years, i.e. until the baby is through nursing and can walk and run. Then the love bond releases the more powerful ones to find stronger partners to impregnate with his/her genes.)

# Best friend or companionate love --this lover enjoys the companionship and intimacy of a close friendship. It is a comfortable, slowly developing, trusting, committed relationship, not intense excitement, desperation, or sexual obsessions.

# Unselfish love --the lover is devoted and self-sacrificing to the loved one, gives without expecting anything in return, is gentle, caring, and dutiful.

# Logical love --the lover carefully selects the "right person" logically, looking for someone with compatible interests, similar education and religion, a harmonious personality, common values, and long-term goals.

# Game-playing love --this person may be charming but is hardly a lover; he/she merely enjoys the dating game. He/she relishes the meeting, the impressing, the seducing, the challenge of a conquest but usually makes it clear there is little or no long-term commitment to the other person.
