What Does It Mean To Stay Until You’re Happy

My question today is about staying in a situation until you are happy in that situation. I am trying to understand what this means and how it should look. I want to leave my marriage, but I want to take my time and be prepared for being on my own with my son, while also trying to make sure that I achieve this status of “happy” before I go. I don’t like engaging with my husband in any way: physically, in conversation, in our business. I don’t feel like we share any common ground, and I do not respect the way he is choosing to live his life. Please help me to understand this concept in how it relates to my situation. Thank you.
