How do i respond to this text?

ignore it

Tell him/her: "you're waiting until it's final? Hmm... I guess I could have done that, too"

Jk. The only purpose, that I can see, of telling you that is to anger or sadden you. You're getting divorced. There is no reason to show him/her you are affected by their attempt to wound you. Ignore it.

Soooooo, your single?.

Ignore it. Not worth your time. Btw sorry abnout the divorce, you'll get through it :(

I would crush the phone...they are evil.

Ugh wtf my tablet completely betrayed me! Before I made this post I was trying to find something already existing (all I found was stupid stuff like "how to get back at your ex" or " How to get back your ex"). I came here because I wasn't finding anything helpful.
Anyway, he asks to use my tablet just now and the browser loads an article I was looking at TWO days ago about coping with you ex moving on or whatever it was I'd found. Needless to say, I feel kinda dumb right now lol.

Don't give that bitch any satisfaction. Delete text and move on with your life.

Just ignore it. If you must say something then I would say something like, "so what" or "meh, I don't have the time or inclination to care about all of that" or "we're divorced, he's none of my business now".

I tend to agree with Jweezee. I feel like the person could be trying to manipulate you so as to elicit a response of some kind. I think the person could be a gossip who's trying to stir some shit up about you. Some people are addicted to drama, gossips are usually like that, and tend to be quite the toxic people.

It's probably best to not respond. I'm sorry about your divorce, I've been through two of them, unfortunately. I dunno where you are but there's a class that's offered at local churches that might help, it's called Divorce Care. I wish you all the best in your newly single life.

P.S. I'd beware of anyone who's really excited or upbeat and sharing what could be construed as bad news.

I would just ignore it, can't really think of anything that wouldn't be construed as upset/childish because it sounds like she is looking for any reply to make her feel like you still give a damn. I would say "ok then you might want to stop texting other men and focus on him :)" but that probably sounds "upset" to her.. Idk :/

You got it; ignore it. What do you care what she does, right? Don't show any interest in her life; you two are divorced. She's just trying to get under your skin.
My second wife was 12 years younger than the first. My third is nearly 30 years younger than the second. That's how you show an ex what you think of them; old hags, both! Get out there and date beautiful women and think not one thought about what they be doing, because you are having way too much fun, now that you are rid of them.
