I am not married but here are some of the things that i heard. Not communicating:-this is one of the biggest problems that caused many marriages to fail. For example something from your husband's behaviours is making you uncomfortable then tell it to his face. Specially girls don't hold back small negative feelings or go to friend or family or keeping it. This may eat you inside and the swell burst one day. Keep the Springs bouncing:-this is something that usually happens in country like ours specially where sex is a sin.but keeping your sex life active helps you to allocate some time to your partner. Shows the love is not dead. Specially for boys getting rejected from your wife sends a signal that she is not interested anymore. You might say "beka sex selele bicha new...." mnamn but this goes beyond sex.even it's not all about sex it's psychology.
