If you guys talk to anyone in a way that states they have it perfectly together and more than you. Or in a way that states the other person has it together, you are always going to end in an argument.
It states to that person that you have no idea about their life and you base it on a single situation you are struggling with.
Do it many times and you end up with flustered frustration.
It makes it look like you talk down rather than on level.
