It really depends on what the standard is, and what the expectations where at the beginning.
If it’s something that is a basic, required halacha (such as hair covering in 99% of cases), it is likely different than something which is a chumrah (such as always wearing tights, or wearing sleeves down to your wrists.)
In any case, when it comes to matters of religion, a Rav should be consulted. If it’s causing tension, it’s helpful if the Rav is knowledgeable in counseling. If not, ask him for a recommendation for a good counselor who is knowledgeable in halacha, as it’s a main part of the tension.
My Rosh Yeshiva, R’ Bender shlita, told me the following when I was engaged (probably not word for word): “Don’t get too caught up in chumros! I once had a talmud who got married, and had an issue. His wife decided to be machmir and always cover her hair even when they were alone in the house, based on the Gemara that says it’s praiseworthy for the walls of a house to never see a woman’s hair. She even covered her hair at night, sleeping in bed. What was the issue? The husband thought his wife’s hair was beautiful, and enjoyed looking at it. Her always covering it bothered him. They came to me for advice, and I told her that being beautiful for your husband and maintaining Shalom Bayis is more important that not allowing your hair to be uncovered when alone with your husband in the house. It’s a bigger zchus to make your husband happy!”
Of course, this applies, as I said, in cases of chumrah, not basic halacha.
