What are the most important aspects to look for in a long term relationship or marriage? Are extrinsic factors, such as beauty, height, color of eyes, physical attributes, more important than intrinsic factors? What are intrinsic factors? These are not as obvious as the surface attributes of your other half. The inner qualities of a person can be described as the deep-well, attributes of a love interest.
When you are considering a meaningful, long term relationship with a lifelong partner, always give more substance and weight to the intrinsic factors of that individual. Attributes such as kindness, loyalty, honesty, humility, and a willingness to explore a deeper cerebral relationship, are more important than anything that appears on the surface level. If you also find your lover in life to be physically appealing, that is also a nice bonus. Get to know him/her on a more intimate level, and spend time exploring your inner selves, before making a deeper commitment.
