Marriages don't always work out, and that's OK. But when you get another shot at love, and decide to get remarried, there are a few key people you need to announce your engagement to before anyone else. First and foremost, if you have children from your first marriage, no matter what age they are, letting them know they're about to get a stepparent can be tricky, as is telling your ex. Here, tips for announcing the news you're engaged to your kid(s) and ex-husband.
The first person you should tell when getting engaged is your child. No matter what age, children take some time to adjust the idea that you're getting remarried and that they're gaining a new parent. When you do tell your kid about your engagement, make sure it's alone — this should be an intimate conversation between you and your son or daughter; having their future stepparent involved will only muddy the waters.
As for your ex, it's only right to let them know about your pending nuptials as well, especially if you co-parent. You should make sure they're the next person you tell, because you don't want the children you share to break the news to him before you do! It's a simple courtesy, especially because your wx be helping the children acclimate to the change just as much as you are. Even if you don't share children, it'd be rude not to inform them of your engagement. If the situation were reverse, you'd appreciate the gesture as well (especially because you wouldn't want him to find out from someone else!).
