Having a hard time “sharing” my kids.

So I raised my 6 year old alone for the first 4 years of her life.. her stepfather been that daddy she’s always needed for the past 3 years and we have a now 11 mo son together.. I’m really struggling to share my kids. Like I’m so used to being the sole and only parent. I make all the decisions. I do all of the parenting. Etc. Our parenting techniques are very similar. It’s not that we are in constant struggle. That’s not the problem at all. My problem is that I’m struggling to let him just lead! It’s not that I don’t trust him. I find myself redirecting him a lot of time. Every time I feel he could’ve done something different or better, I’m commenting on it. Like it has to be MY WAY or no way. I’m just so over protective of my kids & I conscious parent. So I’m always over thinking everything when it comes to them. Plus I’m just not used to having a healthy man if I’m honest. Like I have a real man y’all. A King! He pays all of the bills. The communication is top tier . He is able to safely lead and guide me & our little family. I’m just not used to all of this. I’m just so hyper independent. I always been that way. I never had a village. I’m the oldest sibling on top of more trauma shit. So Iykyk. but I’m learning to stfu & trust the process & stop being so controlling!! I’m getting better. 🤣 whew, I just needed to vent y’all and see if anyone has ever experienced something similar.
