How to stop thinking about a guy who dumped you or is bad for you?

It is a very good question! I've heard people use different methods and here is one of them: every time this guy pops up in your head try and immediately remember all of the bad things he did for you - either big or small. This method is great for developing "resistance" to the person who hurt you. The good memories are still there but you are not dependant on him anymore. I hope this helps! Good luck.

It isn't inherently bad to think about someone who dumped you. My mother once commented that she thinks about her boyfriends all of the time even though she has been happily married for nearly 30 years. Thinking about him only means that you cared for him, which isn't a bad thing. What can be problematic is preventing you from being happy, or finding a new partner. In this case I feel like the best way to stop thinking about him is to take up some hobbies or social groups. Building yourself and what makes YOU happy will create a scenario where you can feel empowered to be someone outside of the relationship you had. Also you surround yourself with people that share interests with. Seeking rebound boyfriends will not be too helpful, but once you are in a good place, you have a new pool to jump back into dating!

I just tell myself im stronger than that and if he hurts me then i know i deserve better. Ive always been the type of person who feel to hard for guys so if you do the same just think.....you are strong enough to wait what you deserve for

There is a guy in your life who dumped you or you know is bad for you, and you cannot stop thinking about him. Why do you think you feel this way? What are some bad things he has done that will make you realise that it is time to move on?

block or delete him, then start fresh. hang out with friends busy yourself with fun and new things

Try to think about other things. I know that doesn't sound too helpfull, but look at it this way, imagine that he did't exist, would it stop you from making other great memories? Probably not, so compare him to great moments and memories you've had in your life. He will not mean anything for you.

Focus on the harmful aspects of the guy or the relationship. Right now you already know that person is bad for you and you will be much better without him in the future. Take your time to accept it and eventually its memories will fade out.

You can share your thoughts with someone you trust and overtime you will find out that you will think less about the situation or tell that person to stop.

Just give yourself time. Thats all that can help. Try and keep yourself distracted wither with work or hobbies but only time will rid you of these thoughts.

Well this indeed is a bit tricky. If you've been attached to someone, its likely that you have them on your mind. The 'symptoms' subtly resembles that of an addiction. The idea is to let to, not all at once because that probably makes the situation worse.
