In that case, the subtext of the following will sound familiar, even if you don't use the exact words:
"I would like you to do this," one of you says, meaning: "If you loved me you would do it."
The other thinks, "If you loved me, you wouldn't ask me to do that."
"If you loved me, you would meet my needs."
"What about my needs?"
"Why can't you get me?"
"Why do you have to control me?"
High emotional reactivity is a hallmark of this type of conflict. That's when a negative feeling in one of you triggers chaos or shut down in the other. The most intense reactivity is fueled by hormones, which is why we fight more violently when we're young and recede into cold standoffs as we age. Though it grows cooler over time and leaves us numb and passive more than hurt and furious, the conflict never goes away, not as long as we keep loving like toddlers.
The origins of the conflict go back to toddlerhood, with the emergence of a contradiction in human nature - the Grand Human Contradiction - our competing drives for autonomy (deciding our own thoughts, feelings, and behavior) and connection - relying on others with the same contradictory drives for love and support. The autonomy-connection struggle is what makes toddlers irresistible and so hard to handle.
The Grand Human Contradiction inevitably reemerges in intimate relationships, and we tend to handle the conflicts it causes the same way we did as toddlers, with blame, denial, avoidance, sulking, and temper tantrums. We get stuck in the toddler brain - the limbic-alarm system that is near fully developed around age two. In the toddler brain, negative emotions can only sound alarms - something bad is happening! All thoughts reinforce the alarm and all behavior reacts to the perceived horror of it.
The ability to assess (determine how bad it really is), improve, and repair require dominance of the adult brain - the prefrontal cortex, which is not fully developed until mid-to-late twenties. In the adult brain, you can see both perspectives at once. You can feel your partner's hurt as well as your own and realize that you deeply care for the person currently driving you up the wall. In this advanced part of your brain, you have a chance of working out what is best for both of you and achieving what you both want - a sense of mutual caring.
Toddlers have Needs, Adults have Desires
In toddler love, all negative emotions seem to come from "needs" that your partner refuses to gratify. The desire to love degenerates into "Getting my needs met," which means to an equally needy partner: "I have to give up who I am to satisfy you."
When love and desire are confused with emotional need, partners eventually act out the old Bob Dylan song, "I gave you my heart, but you wanted my soul."
The soul of love, like a powerful sense of self, grows stronger with desire and weaker with perceived needs. Desire motivates giving; perceived needs motivate demands. Which is more likely to be successful in love?
Below are the major contrasts between toddler and adult love, elaborated in previous posts.
Balancing the Grand Human Contradiction
When interactions with your partner start to get stressful, shift into your adult brain - focus on how to improve, appreciate, connect, or protect. (When you feel connected, it's much easier to communicate and solve problems.) Strive for binocular vision - the ability to see your partner's perspective alongside your own. Don't dwell on the alarm - how bad you might feel and who's to blame - think of how to make it better.
Ultimately, adults-in-love balance the competing drives to be autonomous and connected by acting on their deepest values more than their feelings. This keeps them focused on what is most important to and about them. They might feel like sulking or zoning out or getting away from a distressed partner, but their desire to improve, appreciate, protect, and connect is more important than indulging that temporary feeling.
If you act on your values, your feelings will eventually follow, as you feel more genuine. But acting on feelings will usually cause you to violate your deeper values (e.g., hurting the person you love), which will make you feel guilty, ashamed, and phony.
We must be in the adult brain to act on deeper values. It's not always easy, but the reward is becoming the person and partner you most want to be - self-sufficient, yet caring, reliable, and able to rely on loved ones. Adults in love understand that their only chance of getting the partner they most want to have is to be the partner they most want to be.
