Sorry that you are going through this. Kids are super smart and can sense the energy very quickly. If mommy and daddy aren’t happy together, the kids will know, no matter how much you try to hide it. Also, if the parents aren’t getting along ..that isn’t a model of a good healthy relationship for the kids to experience either. Kids just need love and affection to grow into healthy and happy individuals. That love and care can exist even if the parents separated. Plus, you should choose yourself and your happiness too instead of compromising. Expecting nothing for the rest of your life isn’t a good value to pass on to your kids. Kids will like you and respect you more once they grow up if you choose yourself and your happiness! I totally understand that it’s important to give your level best to make it work and it’s an extremely tough decision to make, I am just trying to provide a different perspective. IMHO modeling healthy loving relationships is extremely important for the kids to witness as well. Wish you the best!
