All depends on the person you marry
If you marry any person you need to take more responsibilities and less time for you (less freedom) as you need to spend more time with wife
IMO marrying is a not the hardest challenge compared to having kids. Imagine if marriage didnt go well you can always divorce and move but once you have kids its almost impossible
When it comes to pros there are a lot like there is someone to share everything and to support you help you
Even your room wardrobe everything will be much organized and good home made food
these are depending on the person you marry
