You are asking about coping mechanisms and healthy ones at that.
I will skip over the topic of the infidelity itself and go just there where you can find solace and help to yourself, how to step outside of your emotional pain towards what was and what will be, and in the what is now, not as a timeframe but in the moment, where there is only you, your heartbeat your breathing.
You must feel your full self, as you exist now, not only mind, soul and emotion, you need to regain center and the best way to do is reestablish where the physical limits of your self as you exist now, are.
Mapping these borders is easy, as it is your body, your interface with the world.
Remember when you were a child, when it was new and you didn’t quite know how much of your body was and how to control it?
Infidelity trauma puts you somewhere there again, with brain chemistry, but instead of a playful discovery is a loss of identity that your mind never expected to experience again, so it was unprepared. You simply need to remap it and feel it to belong to you again. This will change the brain chemistry fighting with the current system and allowing you to slowly regain your balance, or it could be even immediate relief, that depends on how you respond, but you will benefit immensely nevertheless, as regaining your agency over your core.
Your borders, what they are? Your body size is one, you need to feel where you start and where you end, from the top of your head to the tip of your feet. The skin is your largest organ, the interface with the world, that is also allowing you to feel and experience the right now, use it too.
Yoga is a very good way to get this mapping done, even just 10 minutes of light stretching excercises allow you to feel your body and open your muscles enough for your brain to feel them and release the right chemicals, take anything you can easily do does not need to be fancy, plenty of videos on the internet you can follow, for beginners or more advanced if you so are.
And if you are able use the senses of your hands, touch the top of your heads, feel them gliding over your skin, up to your feet if you can get. Remind dot yourself "this is where I start, this is where I end" just feel the physical sensation and surrender your senses to it u til you are finished.
Breathe work, is also important, breathe like a child. With your belly. Don’t force, feel your belly relaxed and inflating with air, allow it to fill you and experience your senses regaining sensation.
Try it now and see how you feel right after
This is a excellent cope when the chemistry brings you down, it allows your mind to counter it.
