Why do I wake up thinking about my ex?

This may a longing that you have after breaking up. The memories that you treasure may be indirectly linked to you thinking about your ex after waking up. However, things like this take time to get over and it'll take quite a while. I've gone through the same with an ex and it took a year to recover but slowly I realized I shouldn't link him to the memories. I treasure those memories and it helped me grow so I left them as nothing but worthy lessons and through this process, i managed to let him go. So my advice is to take it slow, take it day by day and slowly but gradually you'll move on.

It's probably because you slept with your ex on your mind. If you are constantly thinking about your ex, you may find it hard to move on from the break up.

Probably because you're just in the process of moving on. You got used to him and you might be staring your couple photo before you go to bed (which you should totally change).

You still didn't realize how bad he/she for you, u need to go out and discover your self, find a hippy or something to study then u discover that ur ex doesn't worth a person like you who is capable to do this much

Because that person made a huge impact on your life,whether it be positive or negative. Consider it a lesson of what you DONT/DO want for your next relationship

You're thinking about about your ex probably because you've spent a lot of time thinking about them. You're not yet used to having them out of your life because they were such a big part of it for such a time. This is completely okay, and you can make it through this to the next stage of your life where you're happy with who you are and you've chosen a person you care about to love and be with. If you need anything I'm here for you. xxx Moment

don't worry, it's normal. You miss time you spent together, you miss the one you were with him.Now you are different, he is different. If you think you are still in love tell him, on the other side mybe it's just nostalgia and melancholy. I'm sure, soon you will feel better.

When your sleeping maybe your having a dream about him or thinking about him so you just wake up, that's a possibility....you probably miss you ex and are thinking of your memories together so you wake up in distress

Because the heart never forget someone it once loved every relationship we endure in life always has a mark on our heart may it be positive or negative.

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.
