Why do I wake up thinking about my ex?

Breakups are hard and sucky to go through. Love is a very powerful force which is impossible to eliminate all at once. The weak spots will break off first, and slowly but surely it will disappear altogether. The most cliche saying is time can heal all wounds, but it is not wrong. Give yourself time to mourn the loss of a love, it is normal and frankly unavoidable, but you will eventually not wake up thinking of your ex. Best of luck to you lovely human

You may want to think deeper about this and ask yourself some questions such as: What specifically am I thinking about my ex when I wake up? What about that thought strikes me as significant? What about my ex do I remember most? What kind of unresolved issues might I have with my ex that could be resurfacing? What can I do to feel better about any unresolved issues that might exist?

its a normal thing u shared a part of ur life with him/her so make piece with ur self , but sometime ur the guilt we feel after unsuccessful relationships makes us monitor ever hard situation and keep saying that i should have done that or why didnt i react like that

I've experienced that. It helps to try & break the cycle. You can't help waking up every morning with your ex on your mind, but you can change how you react to that. Instead of crying and letting it cloud your mind by sitting here & elaborating on your thoughts...workout, watch tv, call a friend that you enjoy talking to (not about your ex), etc. The more you let thoughts of your ex occupy your mind, the more you're gonna find yourself waking up to thoughts of him/her.

He left an imprint on you. All relationships do, really, both platonic and romantic. And it's the romantic ones that often leave the deepest footprint on our minds and hearts. It might take a long time to wake up thinking about anybody or anything else, but those memories will fade as time goes on. They might always cling to you just a little, but with each passing day they will fade more and more. You're gonna be alright.

It's probably because you have not closed the chapter and have not come to terms with breaking up. Be content with yourself!

Love can take a while to get over. It is an incredibly strong emotion. Thinking about him/her a few days after break up is definitely normal. You never know, maybe s/he also has you in his/her head.

Because you likely haven't completely stopped thinking about him/her during the day. Alternatively, you may also miss the comfort of starting your day and knowing there's someone thinking about you. It will pass in time.

because you are still in love with him and its difficult for you to get over him.

This is a totally normal thing, to wake up thinking about your ex. It means your subconscious is still thinking about that person, and you miss them in some way or another. Hang in there, and it will get easier with time! Consider talking to a listener about your ex. It's good to get this stuff off your chest.
