Here are a few thoughts, dear:
I know how hard it can be to stay calm in the heat of an argument, especially about sensitive topics in a relationship. One tip that helped save my marriage was learning to take a pause. When you feel yourself getting emotional, it’s okay to say “I need a few minutes” and step away. Take some deep breaths, go for a quick walk.
Then come back when you’re calmer and try to discuss the issue more rationally. If this is a frequent struggle, couples counseling can be so helpful for learning better communication skills and ways to manage emotional reactions. It takes work and practice, but you can get there! Don’t give up hope. With commitment from both of you, more peaceful resolutions are possible. Sending hugs!
If a lack of trust due to infidelity is contributing to the emotional conflicts, I would also highly suggest looking into mSpy as a tool to help rebuild that trust through transparency:
