I will give you some idea, but please process them to see if they fit you.
There are several levels of approaches to personal relations. One is following directions, because of not thinking for yourself. Another level is rebelling, or showing people you don't have to follow directons, and doing the opposite of what people suggest.
The more mature level is to think out the best course for yourself, following the course, and giving heavy considertaion to the suggestions of others.
Sorry about your accident.
Your wife seems like she is reacting to prove you wrong. Her responses are as immature as yours. Someone has to start being more mature, so it may have to be you, while your wife caries on trying to make you wrong for a while, till she realizes she is part of the probblem.
Driving is a temptation to prove people wrong. Blocking people you feel are giong too fast, or communicatingf your feelings to cars you feel are traveling too slowly. I have personally tried to change my make-wrong habits, by driving in a more cooperative manner. I generally stay in the right hand lane, and let people pass, or slow down to let people cut in and out of traffic. I leave ahead of time, so I am not rushed.
You seem to be sayhing that the accident you had was partly your wife's fault, or her relatives, for not stipping to rest, or her not stahying awake to keep you awake. You might try to avoid suggesgting your wife is wrong about anything, unless you arfe in a problem solving situation.
Driving long distances, there are some stay-awake accupressure points, that you maynot have heard of. Each of your ear lobes. By pressing your ear lobe between your thumb and forefinger, for a few seconsds, then releasing, releases some staw awake energy. Squeezing the tip of your tonght between your front teeth for a few seconds also release stay awake energy. I twist my tounge upside down.
If traveling with others, you might have it pre-arranged that you can call the lead car on a cell phone, and request to pull over at the next rest stop, or McDonalds, or Gas Station.
Marriage has a different set of expectations, than living together. The woman youknew, may not have had the ideals of the perfect husband. Now that you are married, your wife has to adjust to the idea of a pretty good husband, instead of Mr. Perfect. But you have to remind her of your good qualities. Take this thread as an opportunity to improve your presentation of your good points.
Apparently you hold down a job. Apparently the job is good enough to afford an automobile and insurance. Apparently you can give your wife consideration to express her disappointment with reality, by sleeping alone in the bedroom. What other qualities do you have?
You may lack impulse control. so you might think of processes that might help you with that skill. I found the Silva Method helpful to me. Search Silva Method. The course is a weekend or a few evenings, and can be repeated, as needed. It is self visualizing, and breathing techniques and relaxation techniques, which can be learned elsewhere.
