In one sentence, describe what the following article is about:

Your ex will probably find reasons to contact you if they’re still interested. Check how often they call, text, or talk to you in person. Similarly, consider if they start the conversation back up after it has ended. This might be a sign they like you. For example, your ex might text you to ask questions they probably know the answer to. They might ask, “Do we have an assignment due tomorrow?” “Do you know if Candy’s party is still on Saturday?” or “I hope it’s okay that we’re both going to mini golf tomorrow.” If they start telling happy stories about your relationship, it means they’re thinking about good times. This is a sign that they might still like you. Listen when your ex starts talking about old times to see if they’re focusing on the good parts of your relationship. They might say, “Remember that time we had a candlelight picnic under the stars. That was such a good night,” or “I still remember how much we laughed at the improv theater. We had such good times together.” When you’re feeling upset, it’s natural for a person who cares about you to make sure you’re okay. Notice if your ex always seems to be there for you when you need someone. Additionally, consider if they’re willing to listen to you talk about your problems.  As an example, let’s say you post on social media that your relative is in the hospital. Your ex might immediately text, “Are you okay?” Keep in mind that this might not mean they like you in a romantic way. They might check up on you because they still care about you as a friend. Typically, you go to someone you trust when you need advice. Consider how often your ex relies on you for advice about their problems. If your ex consistently comes to you, this means they probably still feel close to you. It might even mean they still like you. For example, they might tell you about problems they’re having at work or school. Then, they might ask what you think they should do. Bringing up their mistakes means that they’re thinking about what they could have done differently. This may mean they’re trying to figure out how to fix your relationship. Listen closely if they start talking about what they did wrong, what they could’ve done differently, or how they’ve changed. They might say, “I realize now that I should’ve listened more,” “I really regret talking to that other girl. I’ll never make that mistake again,” or “Since we broke up, I’ve really changed. You made me a better person.”

Summary:
Track how often your ex reaches out to talk or text. Notice if your ex brings up nostalgic moments in your relationship. See if they check on you when you’re going through hard times. Notice if they come to you for advice. Pay attention if they start talking about their past mistakes.
