This sounds like a relationship that may not be healthy anymore. When fighting is the only way that two people can communicate, sometimes you have to evaluate how the communication brokedown, if it can be fixed, and really ; if it is worth fixing. I am currently "stuck" in a pattern of constant bickering with my husband and have chosen to physically separate to avoid causing more damage to our relationship while we both go to individual counseling to work on our own issues. Sometimes when fighting you are too close to the trees to see the forest ( or see the larger picture.) Good Luck
