I don’t need to be married to study Kabbalah, but it helps, especially if the partner supports my involvement with Kabbalah. But in short, continue to study in all situations. It’s the pursuit of one’s soul and one’s efforts count toward it, whatever situation one is in.
It can be done. I think it’s not the priority because first a person should see that he is certainly staying on this path before choosing a partner based on it.
