How do I let go of pent up anger towards an ex?

Keeping a journal works pretty well for most people - however personally, I draw. It relieves a lot of the tension and helps work my creative muscle.

Find healthy ways to vent your anger. Find time trying to relax or even exercise so you can feel better.

When I was cheated on, I was so so angry and upset I started lashing out at my loved ones. I couldn't help it! My best friend suggested I start martial arts to let out my anger, and also learn to defend myself. You could try it too, but of course, only if you wish. You could also hike, do yoga, go for long run every day, boxing, or invest your time doing something you love that distracts you from your anger. Good luck

That all depends on the type of person you are-- are you athletic, artistic, poetic? There are all kinds of coping mechanisms out there! You could go for a run, join a karate class, play an instrument, write some poetry, or maybe just write them an angry, strongly worded letter and crumple it up and throw it away :)

The event is not your fault or your ex's fault. Everyone is doing their best with the resources they are given. The anger may mean a deeper sadness and hurt that you are hiding from yourself. Release that and you can release your anger.

i would calm down and take deep breathes or listen to calm and relaxing music to calm me down or any

Just remember that what is done is now done, this person is an ex therefore it is time to forgive them, just not to forget entirely what pain they have caused. You was happy at one point during your relationship, and to hold onto anything other then that is going to be very tiring for yourself. Finding a way to overcome it is going to be a lot easier said than done, but find the strength in yourself to be the bigger person and to move on

I would recommend a stress ball, or even a group text with friends where you can make fun of your ex together in a healthy manner just to clear away some anger and bond.

Acknowledge that it wasn't meant to be. get closure, talk to him or someone else and vent out about what it made you feel. It will take time but time heals all wounds slowly learn to move on and love yourself more. Always keep in mind that it's not your fault, because you would have done to the very best of your ability to save the relationship.

Remember that they are human too. Everybody reacts differently to a break up, but everyone is affected by them in some way. Just as you are feeling hurt or angry, they will be feeling in some way too.
