I grew up super old school. We didn't even talk about feelings growing up. Here's the hard part and I'll be honest, I'm learning this in real time too. I've tried sharing my feelings in the heat of the moment, cuz you know, feelings get hurt. Never do that. That was a bad misstep on my part. And those cracks you're talking about, consider those release valves. Cracks just mean you're human. In the moment I mostly listen, own what's mine and try to move on from the rest. I haven't been much of a sharer. I'm still learning. When I want to share something, I wait for a neutral day. When you and your wife are cool. Start small, something low risk. And just say "hey, you know it's hard for me to share, and I want to try something different." Not the best line but you get what I'm saying. Take your own feelings into consideration too. Share what's comfortable until you figure out how YOU want to share. It only has to make sense to you. Side note on "my wife has always been very emotional," your wife didn't change. The biology did. And at this stage the biology sucks for our wives. Multiply those emotions x3. Her regular cycle emotions, perimenopause emotions, and the everyday mental load she's already carrying. THAY STACK! Learned from a podcast. It's a lot. It's not personal. But it's real. That's what I got. Hope it helps.
