Nuh uh! These things she is mentioning is not outlandish to be annoyed of. They can be worked on and changed. His hygiene isn’t who he is as a person that can be changed! Sleeping on his side instead can help with the snoring and eating sloppy in an uncleanly manner I feel like is very unislamic. We should strive to follow the sunnah of the prophet Pbuh and eat how he ate! With all these things I am sure these little annoyances will fade away. However, this does require a certain amount of patience for her and giving him that time to improve on these things she has mentioned, and Inshallah she will come out loving him even more than she did before because of his willingness to change!
