I imagine that many couples are having more arguments. Especially if the news is on a lot. Being on top of each other is not good either.
I like to go for a long walk and I find that gives me the space I need. If the weather”s bad just going to the other side of the home for a cup of tea and a book works too.
When each person is taking care of themselves they will feel more positive about their relationship. Exercise, eat right with plenty of water. Reduce time on mobile and internet.
There are plenty of home remedies and if both of you are committed to a healthy lifestyle they should help.
Arguing is frustration at feeling out of control. Trying to take one issue at a time and working out a solution instead of piling everything on each other all at once will help too.
We never had therapy but we spent a month in a yoga retreat in India. There was an exercise we did to improve communication and maturity. You sit facing each other and look into their eyes for three minutes. (an egg timer is perfect) then one person starts (coin flip) and has three minutes to say whatever comes up with how they’re feeling. No interruptions. Then the other person, and here’s where the maturity comes in, while continuing eye contact repeats back what they heard without judging. As in, ‘what I hear you saying is,,,,’.
Then that person has their three minutes to express, and so on. It’s really effective.
Good luck.

I agree that this has been an exceptionally hard year on people....

If you think therapy will help.... You can always go on your own.... It can still help you a great deal?? perhaps

The only person we can ever change is ourselves so it might be a gift to you....

Big hug... I'm sorry that you're struggling right now

Thank you everyone for your encouraging words. I would love to try that!

This has been a hard year, most of us are feeling anxious, sad, scared, worried, and on and on. He refuses to go to couples therapy so go on your own to individual therapy. You can ask for skills to cope with things, situations in the marriage if you want and have a safe place to talk about your feelings. One thing that came to mind that might possibly help is to change how you react when the argument gets started. My husband is way too reactive, he reacts from his emotions when there is no need to react. He reacts because he has a physical impairment that limits his ability to find things if they have been moved, etc. Sometimes it makes me angry because he tends to blame someone else. Otherwise, my husband is a good man, a good partner. Let's say he breaks a glass or can't find something. He'll get upset and reactive and maybe blame me. "Where did you put this, it needs to stay in this place." I read a good book recently and realized I need to not take it personally and see him as the emotional small hurt child which is the place he is overly reacting from. Telling you this gives me the reminder. So how this helps is I don't react to his anger or his "craziness" in the moment. I don't escalate the argument trying to have my needs met or trying to get him to see how his behavior hurts me. This is taking me in a whole different path than I have been before. It takes two to argue. We don't have to. If we can figure out why we react and argue back, then we are miles ahead. I argue back and react in anger because of my hurt child inside, I need my partner not to blame me because of how I was treated as a child. So its my issue inside my heart and head as well as his issue inside his heart and head.
