I find it very easy to talk about everything with my husband (a reason why I married him!). I find it very easy to approach him with things that may have hurt my feelings, and break it to him in a way that won't his feelings in return. We never intentionally hurt one another, although we sometimes miss a step and do cause hurt feelings. He and I have never had difficulty communicating anything.
I do find it difficult with friends to confront them sometimes. I know that my truest friends have never intentionally done anything to hurt me, so I find it difficult to discuss these things. I fear straining a relationship that I really don't want to strain by speaking up in situations that could just be looked over. Although I do find fault in this, because looking over these small things often continue to build, and then the friendship goes beyond repair.
I'm usually pretty good at letting things go. Sometimes, it may take me a few days, but I can overlook a lot. And I have definitely overlooked a LOT over this past year. But I have also realized that most friendships that I have overlooked unfortunate circumstances usually causes more damage in the long run.
I also feel like my comfort to confront usually says a lot about how I value the relationship. With my relationship with my husband-I WANT things to stay as healthy and happy as they are. I've often noticed that I can determine the friendships I value most by wanting to make sure they remain healthy.
I definitely don't bring up every tiny thing, because I am aware that I can sometimes be oversensitive and take things the wrong way. But on the things that really hurt my feelings, I can usually find a way to bring it up. I may even just bring it up in a small conversation and brush over it. It may never turn into a large discussion. I don't find it necessary to make every bump in the road a long conversation. Sometimes just throwing it out there, even lightly, is enough to make me feel better. :)
