Insecurities
With Venus in Libra, when you are insecure about your own selfhood and your own values, you need the validation of others to support your ego and feel that you have some sense of self-worth. Consequently, so much time and energy is spent in cultivating your relationship(s), that you are dominated by your need for others. The all-important role of self in any relationship is lost. Having Venus in Libra, though you seek to enhance your self-worth by being in a relationship, the actual result of your dependency on the relationship and on your relationship partner(s) is that you lack basic self-confidence and self-esteem.
