Back during that trip abroad, this is what I told her, she told me that I'm the man in this relationship and I should stay and escort her back home because I'm not like 70 years old. I said I can't stay as I'm tired and I left (after an angry look for the 70 years old comment).
I wish I did what you suggest during arguments, I'll try to control myself more but I can get in an emotional roller coaster when we're arguing. I can do that with other people e.g. my father, my boss or pretty much anyone else but it's tough to keep my cool with my wife.
Re societal priorities over my health, it annoyed me a lot ... She even dismissed it. She said it happened during the trip as well when I wasn't on medication and even now I'm not 70 years old, other people have the same condition (nobody she knows or anyone who was at the social event but nevermind).
Still I was the one that blew things up... she wasn't being considerate but it was me who went too far and said to my (pregnant) wife that I want a divorce.
One thing I need to mention, besides the "I started it" argument is that I must not upset her during pregnancy, it can affect both her and the child. A negotiation on boundaries is perhaps better timed for the months after the birth.
Actually, you should state, "I am tired, and I need to go and rest. If you want to stay, please do so, but as for myself, I am drained and rest would be healthy for me."
Even in arguements,, you can say, "We both are highly emotional at the period, do you mind if we talk about this at another time? We both can think about it and we can talk about it when we are both ready."
There is a point where you can enforce boundries before things escalate. You allow yourself to get to that critical point where your emotions control your actions.
Perhaps, you can learn to see the signs of escalation and defuse the situation.
But, listen to Blossom, her societal priorities came before your health. Right now, you have a drive to be with her and do you think because of your feelings at the moment, it is blocking your perspective?
