If you ever get a text like that, do yourself a favour and delete that number. They’re not interested. They’ve moved onto other things. Do the same. You’ll be a lot happier.
Let’s make one thing clear: revenge is never a good thing to crave. It only poisons you. It eats at you. Use that energy to achieve good things and attract more good energy. Think happy thoughts and find the next big adventure awaiting you. But don’t waste your time getting back at your ex. They’re not worth it, and you’re so much better than that.
