Was my behavior wrong when I asked my friend's fiancé to respect my presence while he was visiting her in our shared home?

If the legal marriage contract (aqd) has been concluded between the man and the girl, then she is his wife, and everything permissible for a husband with his wife becomes permissible for him with her. There is no harm in him laughing or speaking with her in the questioner's absence. The agreement to delay consummation, if it exists, should be observed, though it is better to complete the marriage without delay. The questioner should not sit with them unless there is a need, and she must adhere to the Islamic guidelines of modesty and covering if the man is not a mahram (definition), and she must repent if she has not done so. She should not leave room for Satan to create animosity between her and her friend.
