One year in but a newbie

[Lifes Twists]

That is what I am struggling with right now. I am not sure about the love anymore. The more I ave been able to detach and get some distance, the more I question myself.Having spent so many years with a severely depressed person who always seems to look for the negative in everything I am starting to question whether I can stand it for the next period of my life. yesterday email from W she complained how the 2 older girls had not gotten along with each other throughout the entire time that my oldest has been home from college on winter break. I had just gotten a text from my middle daughter that she and her older sister were on their way to have lunch together. My perspective is the kids are just being kids and having the usual power struggle that siblings have growing up. My Ws is that they have been fighting the entire time. She always blows everything up into a huge negative. How does one respond and live with this?
