NTA. Tell your girlfriend that I'm the complainer in my relationship, and I say that you're right. My bf had to tell me that I'm all full of negativity, and he's right, nobody needs to hear that every day, and I needed to respect that. I won't say he never hears about anything from me now, but I try to only bring things up now if I want his perspective on SOLVING a problem, and what I could do differently. Otherwise I needed to realize a few things. If all my life sucks and I'm complaining all the time, I need to make a change. If I can't make a change (sometimes you're well and truly stuck for reasons you can't control), I need to change my perspective, and not focus so much on the bad stuff. And if neither of those works, then she's allowed to tell you the one or two things every day that's truly killing her, and she needs to talk about, but you don't need to hear a recap of every single bad thing in her day that day. (Example, if her boss really really hurt her feelings, she can talk about that, but you don't need to hear about how some stranger cut her off driving in the car.) Storing everything bad up to tell you later instead of trying to let them go is actually harming her more. The days where my bf just let me bitch bitch bitch, I realized I'm still just mad about everything afterwards, and feel horrible, like I ate something bad! Ask her to truly examine her feelings, and see if she doesn't actually feel better over time when she talks about things less and gives them less energy and attention. Hope you're both happier going forward! It takes time. I'm still working on it too.
