WHAT DO YOU THINK ABOUT SPLIT UPs

My husband and I are not getting a long. Trust issues. Have been getting along a little for 2 years since it happened. But now for some reason we think we need time apart to breathe and heal without each other. We have two boys. 5 and 11. Are hoping to keep it civil. I’m wondering if anyone has experienced and healed and ended up back to being married to that person. Or is it a lost cause and it will end. what do you think ?
