Relationship is basically supporting each other. Every individual is different from one another and they have different need. But on can simply it by saying most men look for moral support and encouragement from their partners while women look for care and affection..
This is just generalisation.. but when it comes to real deal there are many factors that comes in play.
Understanding
Trust and Honesty
Sex
and many other things
But perhaps the most important thing is future..
Where do you wanna take the relationship?
You can't stay at same place because with each passing moment you are changing and your partner is too so, things and dynamics between you and your partner will change and by future mean how to do you want to handle the changes and whether it means the same to your partner.
