I’ve heard too many people I know recently saying something along the lines of “I’m having this problem with my partner but I haven’t talked to them about it.”
Just talk. It won’t be comfortable, talking about conflicts never is. But you know what’s worse? Festering. Because it will fester. Don’t think you’re good at communicating? Talk about it? Don’t think those conversations are going well? Talk about it. My tentative term for this is hyper-communicating. I am not sure it is possible to over-communicate. So just communicate and communicate more. For the love of your partner. Please.
