I am amazed at how many people so flippantly tell someone else to get divorced.
I must say it does sound like there is not much maturity involved so far.
If you love someone enough to marry them, you should be willing to put some effort into the marriage. Give it a couple of days to let your heads clear and have a discussion about what is really going on. Then start the decision process for determining where your marriage is headed.
This isn't 1961, Beaver.
Since when has maturity been a tenet of society?
