BS"D Dear Rabbi, I was watching your recent shiur on the 3 weeks and you mentioned that where there is Kidusha the Sitra Acha makes problems. I have heard this concept before and understand it but never applied it to my marriage. Can you please expand and go into more depth on this concept please? My Wife and I are having Shalom Bayit issues mostly over Spiritual/Religious growth and Chinuch/Hashkafa issues and when I heard you say this I felt that this concept could be applied and may be what's happening to us so I would like to learn more about it and to see if you have any sound advise that I can use to help my situation. I am Sephardic Orthodox and live in Brooklyn N.Y. Thank you for your time and I look forward to your reply. Kol Tuv
