I wish I was better at conflict, especially with my partner. It gnaws at me constantly if unresolved, gives me horrible anxiety (I'm normally not an anxious person) to the point where I can't eat or sleep. So, I tend to hold back from conflicts altogether. Not a useful solution. I wish I had better advice to offer but in place of that, please accept my commiseration. Hopefully some time to reflect and cool down will prove useful and perhaps your partner will have fresh ideas for resolution when you readdress it.
