You'll share some specific needs as to the type of commitment and togetherness you'll want to create with each other, but those needs will be at odds with your deepest emotions and urges for personal transformation. You might want or try to go deeply together into your own interiors -- the parts of yourselves that are powerful and passionate, and ready for transformation -- but then you'll somehow misuse the things you learn about each other. Instead of supporting each other through this intense and vulnerable process, you might manipulate each other with what you've learned, or otherwise get mixed up in power plays.
After all, facing your own inner demons is difficult, uncomfortable work under the best of circumstances, as old hurts and anxieties flare up anew, demanding that you process them thoroughly. But your tendency to try to control or even shame each other will work against your shared urge to commit to your relationship. This situation does offer you an important growth opportunity, however. You'll need to work together to recognize that the point of your relationship shouldn't be to gain the upper hand as you control or manipulate your lover; it should be to get to know yourselves better while becoming a closer, more committed couple in the process.
