married Redditors, what should we know about marriage?

Healthy communication and trust is key.

That fights and arguments aren’t normal. Disagreements, yes. But disagreements shouldn’t become arguments.

That you’re supposed to both love and like your spouse.

That your spouse should be your best friend.

Edited to add:

You should also have a healthy mix of mutual and differing interests. You should also take an interest in your spouse’s differing interests.
