Eros
Eros is a passionate and intense love that arouses romantic feelings; it is the kind that often triggers “high” feelings in a new relationship and makes you say, “I love him/her”. It is simply an emotional and sexual love. Although this romantic love is important in the beginning of a new relationship, it may not last unless it moves a notch higher because it focuses more on self instead of the other person. If the person “in love” does not feel good about their relationship anymore, they will stop loving their partner.
This just offers you a general understanding and description of the four types of love which promotes a good, healthy and progressive relationship. In any relationship, you should have all these four loves working together to enable it survive for a longer time. But in some cases, a relationship may be long-lasting if partners share the same style of love.
