:salam2: sister
Firstofall, congrtulations for embracing islam, and alhamdullah that Allah (swt) guided you.
Muy humble opinion would be. to follow the Qur'an and Sunnah and avoid doors that may lead to fitnah.
I am not married, but I would honestly refrain from anything that would cause my marriage any harm specially if my wife wouldnt be happy if I continue with friendship that she may feel inappropriate.
But for me to continue this frienship, I would introduce her my wife first, and may be invite her and her husband for a dinner at home, that would look more respectful, specailly to my wife. I would call her husband and invite him and his wife (my friend) for a dinner at my house. But, if I feel any of my actions might lead to a negative result I would immediatly refrain from it.
But, I wouldnt go out with her as a friend for a dinner without my wife, and I wouldnt speak to her in the absence of my wife either so that my wife do not feel jealousy, or develop emotional problems that may ruin my marriage. In many cases, this would also lead to endless questions and suspicious.
I dont like if my wife had this type of friendship. Therefore, I wouldnt continue with this type of friendship if its against Qur'an and Sunnah, and if it is based on islamic behaviour and clean intentions I would follow the most appropriate manner without causing my wife any emotional harm. My wife would come first before any frienship, her emotional health comes first, and my marriage is above any friendship.
Wassalamu Alykom...
