There are people in the world who require a partner to help them through life, but they are not necessarily looking for love. Living together is often their goal, and they seek someone who has strength where they have weakness. A personal partnership is important for them to live a good life, but they may have difficulty feeling an emotional attachment. This type of person is looking for a permanent relationship without emotion being any part of it, but they are capable of commitment.
Seeking a partner for this type of relationship has been difficult in the past, but online sites are now available where people can state exactly what they seek. This does make it easier to find people looking for the same thing, but they may not always be compatible. Love and affection are often the glue that holds people together in a relationship, but this type of arrangement only has need to make it work.
