I don't think it is a guy thing. Depending on what kind of conflict that you are talking about. For me right now I try to stay away from conflict with my W as much as possible. But when things need to be talked about I go and do it. If there are issues with bills and stuff most will take care of that.
The reason that I don't get into conflict with my W is because she seems to get very angry about things. So I am trying to find ways that will allow us to talk about things more as adults. Im really trying to strike while the Iron is cold.
