Semi-Related, but was this one unplanned? If not, were you trying for a long time? I've seen couples try for 1 month, some for 8 years. It changes the dynamic of the conversation.
The cliff notes version of this, shes a hormonal trainwreck. Take it all with a grain of salt-unless this has been a topic for a month and not just a fleeting statement she made as this thread suggest.
But, in either circumstance, the best way to make it work long term is WIFE above all else. Family, Kids, Cars, all of it. After all, you literally made that legal commitment to it. May as well follow though lol.
But for a more practical reason, if the marriage sucks-the rest of it will suck anyways.
