Unrealistic expectations are,among many others,to expect your partner to anticipate problems and not communicate clearly your emotions in the hope they will guess things just because they love you. Treat your partner like a parent is the biggest poison you can give to your relationship. Your wife is not your mom, your husband is not your father. Something else that is very recurrent is to be jealous of your partner’s past. We all got a past. Even a 5 year old has a past. Instead of being worried about how many guys she has slept with or how much in love he was with his ex, pay attention to now, make the relationship work out, because we are not that young anymore and we all should be glad our partners have a past,for,without that, they wouldn’t be who they are now.
