I'll start with one of the toughest for a couple to work through...

She believed he was a man, but he now believes he's a woman. It happens.

What beliefs could partners have or develope that could put a wedge in an otherwise happy relationship?

The belief that love conquers all? It takes a lot more lol

Well if you get one of those creeps who thinks only
their less-than-bright political opinions matter
and you need to follow along, I am not sure it can be
worked through.

If you got one of those rabid types, best to jettison
early on I think.

Right up there with finding your man is really a woman.

She believes the remote to the TV should be shared.....while he believes that this is breaking the 11th commandment.....you know....that one commandment that was left out of the bible all because Moses fell asleep and forgot to write about it.

Maybe we should check for mental problems before we start a relationship... The whole thing about relationships is finding things out about each other,. Hopefully good things, but not always... She should drop him off at the local insane clinic and speed off...

Good One!

At least he didn't fall asleep with a death grip on the remote.

Well this was God's punishment to all women.....man shall fall asleep with a death grip on the remote....the channel stuck on so soft core porn....darn you Moses!

And then there was football, and the Lord gave unto woman the universal remote and bade her go forth and root for the team of her choosing for all the days of her life.

The belief that a third person in bed would be acceptable...

Or that it's okay to replace the significant other in bed for temporary fun when they want to spice things up...

The belief that it's okay to natter on about your day when the game is on the telly.

Different beliefs on how to handle money.
Different beliefs on how to raise children.
Different beliefs on how to treat others.

The worst one I think I've run into, is also among the most sneaky and insidious.

It's the belief in their core, that they have to like everything about living with you, and that anything that isn't fun, is proof that they are with the wrong person.

Skip out on the ironing one day, and they are on the phone to the divorce attorney. Fail to properly please them on some official holiday, and your spiritual status is called into question.

It sneaks in, because at first, they present it as a positive sign that they believe in you: "I know that you WILL do this trick right in the future, because you are so wonderful!" But later, that same "faith" changes sides, and they start tallying up each "failure" on a tote board, and you can never catch up.

My ex wife was still bringing up mistakes I'd made and holidays I'd failed to get a nice enough gift for, twenty years after the events.

I know people who, as a rule, don't talk about politics on dates.. I think this is a mistake unless a vow of political silence is worked into the wedding later. Eventually it will out, and what then? Could be chaos.

The belief that "You should know how I feel"...therefore there's no need to tell you. The belief that you don't need to reaffirm what is/was already established or should be naturally be known.

Right along with believing you know how another feels and what they think without question.

Although it is ironic that some relationships depend on not finding out what the other feels, thinks or believes.

i have a name for them....relationship perfectionists. Though the perfectionism tends to be very one sided.

as long as it is on the little tv in the den that has no sound

I think people tend to prepare themselves more for the first two than the last. Since the honeymoon daz-phase can keep this tendency hidden for quite awhile, it isn't until you're fully invested that you discover you may be with the rudest most obnoxious human on earth. I know the shock of that myself.

while it's not really a belief. i think one of the biggest stumbling blocks, is the masks we all wear and getting stuck on the mask not all of each other.
