Marriage intimacy (into-me-see) is of two parts: acknowledging your own wounds (shadow self, character flaws) and daring to expose them to your partner. Until you have seen the other’s shadow, you do not know him/her, and it is unwise to marry someone unknown. In fact, this is the best answer to the perennial question of how long is long enough to be in relationship before committing to marriage: until you’ve seen it all. The shadow self is always the last to emerge, despite best efforts to hide or deny it forever.
First things first, however. There is nothing to own and share that you do not first see in yourself. One sacred text calls it “the plank in your eye.” Marriage aside, any progress in personal or spiritual growth starts here. Think of Socrates’ axiom on the unexamined life. Yet rigorous honesty with oneself is very difficult. Your ego has to be strong enough to survive the come-down without crumbling and humble enough not to veto the entire project. Ordinarily, we would defend against such critiques, especially when they come from outside. The key is to stop playing the worthiness game. Your worthiness cannot be a character judgment (by anybody); it has to come from something larger and/or more intrinsic. Some call it grace.
The second step is also not automatic. Disclosing the nature of your woundedness is a risk, a dare. The central question is – will your partner be a safe guest inside your tender truth? Vulnerability refers not to the wounds revealed but to the possibility of new ones. The trouble for many couples is that one or both partners are not safe. Safety in this context means listening without judgment, without righteousness and without exploitation. To grow in intimacy is to slowly reveal yourselves to each other, building trust along the way. One threatening response can set you back a long way.
The opposite of intimacy is estrangement. All of your problems are external, “over there,” in your partner, who is simultaneously thinking the same way. Marriage becomes a scapegoat system rather than a support system. We get married to have a very close-in support system, for which intimacy is not just an asset, but a pre-condition.
