I agree. I'm in the same situation where my bf never saw his parents even raise their voices at each other but my parents constantly fought so my raising my voice even a little is equivalent to yelling to him.

Its probably not about whether someone did something "wrong". Sounds like youre just not right for each other. My T told me something one time: that everyone has their own communication "style". Mine is straight forward and kind of abrasive. he said there is nothing wrong with that but most people are not that way. Most people beat around the bush and don't just come right out and say what's on their mind. So most likely I will not find a guy with my same type of communication style. So the best I can hope for is someone who is not intimidated by it and someone who can learn to deal with it an vise versa.

So the deal is whether you're willing to find ways around the communication disruption and figure out ways to communicate better. If you're not that into it, then I would leave. And, honestly, coming from a home with 2 divorces (my dad and mom and then my dad and step-mom) I can guarantee you my life would have been more disrupted if they would have stayed together. It's way worse to watch 2 people fight (especially when it's your mom and a potential father figure) than it is to go through a divorce. Keeping them in a situation where there is fighting and misunderstanding will do more damage than just leaving. I know its hard. just know were here to help! Good luck
