Generally, what human beings think and do can be traced back to a cluster of habits formed during his/her early childhood. Then that will mean that we are our habits. Maybe that could explain why it is so difficult to change or stop our ways. Relationships of people are also impacted, hugely, by these.

Do not take each other for granted
Your partner might be caring and loving but always remember to appreciate each other and thank them for even the smallest things that they have done for you. It's always silly to constantly thank your partner for every little thing but keep that respect and love alive for each other.

Blame games
Do not try or put the blame entirely on your spouse or partner. The mess might have developed because of both of you but do not point a finger and accuse your partner.

Nagging too much
Men become dissatisfied most when you keep on nagging. Do not nag your partner always as it would always spoil your mood and the friendly atmosphere between you both.

By not taking care of yourself
Take care of yourself first to become a good partner. The best partners are those who cultivate care and concern for emotional, physical and spiritual health.
