You can get married on the bot by purchasing an engagement ring from either /shop view or the /market.
After you purchased an engagement ring, you can start your marriage with someone by using the /use item:Engagement Ring user: command, the other person of course has to be around and accept this proposal in order for it to go through.
Keep in mind, both the parties of the engagement need to be level 25+ or prestige 1+/omega 1+ on the bot.
Marriage brings a couple benefits and downsides. To view these, you can use the /marriage levels command.
The benefits/downsides are:
You can keep your marriage up by interacting with your spouse before your /marriage view hits 0.
You don't instantly lose your marriage if your /marriage view hits 0. At first you lose a marriage level for every day the love is empty.
If you or your spouse's love is empty (0) for 5 days, you will be divorced.
The following interactions count for upkeeping your marriage:
/friends share command;/game with your spouse;/use item: Cell Phone command.
While having your marriage up with your spouse, you also can "create" some babies with them, this is completely at random.

If you fail to interact with your partner before the /marriage view reaches 0, you will end up divorcing your partner.
If you wish to divorce your partner yourself, you can also use the /marriage divorce command to do so.
