It’s a phase
Introducing baby after so long is a real gaaaaaame changer!
Things change once you add a baby to the equation. You both just need time to adjust, also counseling.
That’s how my marriage ended. I communicate always. No one can ever say I didn’t tell them something, attempt to discuss an issue, or anything. My ex husband and I had been going downhill for awhile but one particular night we were getting into it. I was calm, I spoke soft, maybe accidentally smirked because I had just had enough and I said “okay. So are you telling me you will not talk about this and come to some kind of compromise together?” And he responded “no I don’t believe I did anything wrong” and I said “okay, then I’m done. It you aren’t willing to work together to fix even the smallest issues then you are clearly done as well.” And I packed that night. And left.
I’ve been going through something similar with my partner, I am pregnant and we started going out on dates again and I feel like it has been helping so maybe u both need abit of time together on ur own, go cinema or for a meal if u got the means to do that e.g babysitter etc. I hope everything get sorted x
