Keep quiet about your relationship in conversation with others, but always tell your partner right away if something doesn't suit you.
Problems in relationships are like a snowball made up of small problems that it was decided to ignore.
Don't leave the room, if you don't like something, just discuss it with your partner. Don't be silent, don't you dare cross the threshold until you discuss it. Trust me, it will save your marriage.

Don't tell your friends about relationship problems.

Do not be silent about these same problems when talking to your partner.
