Her husband sits with non-mahrams and she objects to that

We begin by thanking Allaah for this
gheerah (protective jealousy); may Allaah help you to enjoin what is
good and forbid what is evil. We advise you to continue with what you are
doing of advising your husband and his relatives in the best manner, until
you find among these people someone whom Allaah will guide at your hands to
give up these haraam actions. In this way it will become easier for those
who think that they are weak and unable to change, to mend their ways and
adhere to the commands of sharee’ah. You have to seek help in your efforts
to advise them by praying to Allaah for these people, being kind to them and
not acting superior to them, but rather showing kindness and compassion
towards them, because that is more likely to be accepted and this is
something that may earn their respect despite your young age.

 In addition to that, you must also strive
to avoid joining them in the wrong things that they are doing, lest you
yourself weaken with regard to these evil actions, especially the bad movies
that you mentioned. The believer cannot assume that he is safe from
temptation, rather he must help himself to fight it by keeping away from bad
things and by making du’aa’.

 With regard to what you said about feeling
sad, jealous and angry for the sake of one’s religion, this is a blessing
from Allaah to His slave – but these feelings must be controlled according
to the guidelines of sharee’ah. Sadness should not lead to despair and so
on. Allaah said to His Prophet (peace and blessings of Allaah be upon
him):

“So
destroy not yourself (O Muhammad) in sorrow for them”

[Faatir 35:8]

Anger should not put off those whom
you are calling, for the purpose is to reform him, not simply to express
one’s frustration and anger.

 So long as your husband is a Muslim who
prays and is kind (as you mention), then be patient with him and continue to
call him (da’wah); perhaps Allaah will bless you by guiding him and causing
him to follow the ways of chastity.

 Perhaps if you think about the calamities
that have befallen other wives who have suffered because of husbands who are
worse than yours, that will make you put your husband’s sins into
perspective. We ask Allaah to guide him and you, and to guide us and all of
mankind to that which He loves and is pleased with. And Allaah is the Source
of strength.
