"Talking" to your SO.

I see a lot of posts on here by women who are confused by their SOs actions. Or, they're tired, and sick, and upset over what they feel like they can't change by their SO. I frequently see women comment saying, "I think you should talk to him about it." As in, when you're uncomfortable with him doing or saying things, or mad or upset over it. It could have to do with other women, his friends, his bad habits, his career, maybe he's abusive. Anyone else want to "talk it out" with their SO but feel annoying by now? I feel like I used to be able to talk to him about issues we have. Now, I feel like we have so much that it's annoying. I annoy myself honestly. I get jealous over nothing and I want to "talk" about it but it makes me look crazier and crazier so it eats me alive inside to hold it in. Any other solutions rather than talking about it?
