A major factor in shidduchim that requires attention is that people are afraid to do things because it might ruin shidduchim and once married become partners in ‘crime’… If you feel sth is right there should be nothing stopping you from doing it and conversly if you REALLY feel sth is wrong don’t start doing it after marriage…
