You don’t really provide a lasting solution. First off, everyone is broken. Everyone. Your partner. You. Every single person on this planet is wounded. Why? Because everyone’s parents are flawed human beings. To try to use someone else as an object to heal yourself is not only useless (they’re just as flawed; stop idealizing them through projection of desire), but it’s incredibly selfish and narcissistic. Love is not need. Love is a gift we give.

Now, not everyone wants to hear this, because your rational mind may be overwhelmed with the perceived need and the false hope that the void can be filled by another. But perceptions aren’t always true. As you say, look to the cause of the pain. It’s your responsibility to identify it and overcome it.

Only two real solutions are known: the Freudian, which is to overcome the void by ceasing to chase after things to fill it with by accepting the despair resulting from the acceptance of the fact that it cannot be healed by anyone or anything. The other begins where the Freudian leaves off and looks to God for unconditional love, the kind no human being can truly give. God becomes the perfect father and parents, infinitely patient, infinitely forgiving, infinitely loving and nurturing and protective. But that requires a belief in God. In both cases, however, one must learn to love oneself completely and unconditionally that that healing can occur.
