because humans in general are weak minded filth, the thought of walking through life alone scares them - so they seek partnership and assurance, truth is (for me anyway) "love"/human contact is not more important than money, health or physical development, humans are needy in nature so as you said even though we try to mask it, its the selfish and weak minded part of us that longs for "love"

dont get me wrong, i one day hope to meet a "the" woman - but no way in ****ing hell am i sacrificing money (eg job oppurtunity), my health or my physical activity (eg boxing or weights) for her, and if i dont find "the" woman i will be alright, i survived the first 23 years alone, another 23 wont ****ing hurt me
