My $0.02?
The first year or two was stressful for my wife and I and we finally 'got things down' I'd say by year three of four.
So having little spats like this that turn into large sources of contention is of no surprise to me.
A few things to consider here:
1. The marriage is new, & you have to find and set boundaries, spoken or otherwise
2. How old is your wife? You are only 23, correct? Age can be a factor as well
Have things always been like this? I ask because of this last point:
3. She JUST HAD A MISCARRIAGE! That is HUGE. Marriages can break up just on that fact alone.
When my wife had her miscariage, it threw our whole life in chaos.
Actually, that's when I finally started to question Jehovah and the organization that I thought was his representative org on earth, and hence, put in action my DA.
My wife went through a multitude of problems. One major issue she had was she thought that the miscarriage affected her more than it did me. Which it did, because she was carrying a life in her.
With you giving mention to the miscarriage in just one sentence leads me to think that this issue has not been addressed and it's danger is not fully realized by you.
The miscarriage can be a festering problem that could infect the rest of your young marriage unless it is addressed.
Many women will NEVER FULLY get over a miscarriage until they have a child of their own. And just seeing another woman with children or pregnant can send them back into depression.
This is all just based on my own experience, so I could be wrong on alot of things here since I don't know you or your wife. But at least it may give you another perspective that you may have not considered before.
Best,
Paul [Winston.]
