Something that I did with a boyfriend when we were having problems communicating was a shared journal. We were arguing a lot and neither of us was listening to the other, so we were both fighting harder to get our point across and be heard. So we took a notebook and wrote journal entries. I kept it for a couple of days and would write about my feelings and my perspective on things that were going on. And then I would take it to him and he would read what I wrote and then he would write his own entires and bring it back to me. These were not letters back and forth to each other. They were journal entries. So we were using "I" statements about how we each felt about what was going on and about each other and about how it made us feel when xyz happened and so on. But by being able to read each other's thoughts on our own time and not in the heat of the moment, we were able to process what the other was feeling and get a better idea of what each of us needed from the other. This didn't replace talking. But our communication improved greatly by doing this. We tried to remember not to penalize each other for what we wrote in the journal because we were each entitled to our feelings. It just made them easier to express because we could think about it a little instead of saying things in the heat of the moment.
I hope that you and your SO can find a way to work things out. It sounds like you love each other very much.
