18 really important things that no one tells you about divorce
You're braver than you know
You're going to hear a lot of people telling you that you're taking the easy way out and that you should suck up all the hurt and sadness because you took vows or because it's better for the kids. Ignore them. It takes a huge amount of courage to stand up and demand a better life for yourself, your kids, and, yes, even your ex. Making a change is always harder than sticking with the status quo, so be proud of yourself.
As for the kids: They deserve to have happy parents who can actually be present for them - and they deserve the chance to see what a healthy relationship looks like so they have a shot at having one someday, too.
