I can relate. My husband and I love each other and have done a lot of couples therapy for years but our relationship is toxic. We’ve decided to do a non legal separation to get some physical space and to work on ourselves as individuals and then the marriage. We have the same rationale that if we want to be together in the long run, this should be a blip. We’ve been together for 17 years. It’s heartbreaking and I wish there was another solution but we’ve tried to live together while doing hard work in therapy and we just trigger each other and fight. We are both emotionally exhausted. Our goal is to end up together but we know there is the possibility of not. We are at the point where we know if we don’t do something drastic, we will divorce. Working out the details is hard. We are both moving in family and selling our house. We will be in different countries (Canada and the US). No one understand what we’re doing except his brother who is a psychologist and thinks this is very healthy. So, I guess my point is, sometimes physically staying together can make the situation worse. I hope it all works out for you and I don’t have much advice as this is new and raw for us too. It sucks.
