I mean, I know what not to do. I don't scream/yell, blame the other person solely, use words like "always" and "never", name-call, throw a fit, etc. I try to say "When you do this, it bothers me because...." or "I feel x because of y", etc. Are there any other tips that have helped you "fight fair" with an SO, or what not to do? How do you know when you should say something at all, and when you should let it go? Generally I try to keep a positive persona, and I know that not every little thing needs a reaction, but I also feel like it's not a good idea to keep brushing off issues that continually bother you. Thoughts?
