It isn't about the kids. The kids will feel shit about it, sure; but they'll get over it.
When people say stupid shit like "Stay together for the sake of the kids" it makes me want to slap them. For the sake of the kids??? What do they even mean by that? Do they genuinely think it is healthy to teach kids that they should stay with someone even when they no longer love them? No, if it was about the kids at all, it's better to teach them to understand that if they aren't happy, they can change that and let themselves be happy again. Being miserable with your life wouldn't do your kids any good at all.
But it's not about the kids, it's about you doing what's best for you. This is your life and you're not going to get another one, so do what's best for you.
