...when it's time to split up? DH and I argue all the time. I feel like we cant talk about anything anymore. Ds goes to university next year and DD15 is pretty independent so wont be long until she also leaves. I am dreading being without the kids. We have been together nearly 30 years, our lives are completely meshed together. I have no desire to be with anyone else and I dont think he does either, but we do not make each other happy any more. How do you know when it's time to split?
