How do I know if my ex is thinking about me?

You don't need to think about your ex anymore. The past is past you have to let it go you can't continue on thinking about the past anymore you have to live the present moment and forget about it.

they constantly message you or they act they same way they did when they first flirted with you :) it's obvi then.

There is no way to know this, even if they tell you because they may lie for a wide range of reasons. It would be better to try and not think about this as it can cause a lot of distress.

That’s easy. If he checks your social media, likes your photo and texts you back. Also if he gets jealous. Sometime they might not show it though.

Many times we can overthink and then it can upset us. We may think that something someone does is meant a certain way but it really wasn’t. You can never know 100% if your ex is thinking about you unless they admit it to you. However just think about what type of person they were when they were with you. Would this person think about you? Why did your relationship end? Sometimes reflecting on the type of person they were when they were with you can give you an idea of whether this person would take time out of their day to think about you.

Never think about it. Or even dream about it. You must move on in your life. You have things bigger to think about it. Not your ex

Your ex can and will think of you sometimes. But not always in a good way. They might miss you, they might think of you when thinking about all of their exes, they might think of you when they go to a place where you were. Those are random thoughts that pop up to everyone. Now that you know this, ask yourself why are you thinking about them. Is that good?

The best way is if he contacts you. Another is if someone tells you he was talking or asking about you.

If you both really loved each other and if you still have trust in your ex then surely your ex is missing you. No matter how your relation was good or bad you always think of your ex because if it was good u have memories and if it was bad still you been remembered by your partner. so just relaxed be clam and focus on your life. past is just going to give you trouble . If she is really meant for you the she will be back to you no matter what happens. Enjoy your life focus on your career.

You can't :) Well, I would suggest you shouldn't. If you are really over him/her, you should start the healing process. Thinking about whether your ex is thinking about you or not will be an endless process and won't result in a yes or no answer because you cannot read their mind. It will never help you move on because you will keep obsessing over it. So rather than putting yourself through this, you maybe want to distract yourself with some new hobbies or friends so that you don't keep thinking about your ex and lose your sanity and sleep over it :)
