How could a relationship last long?

Understand each other. Learn to accept that nothing's permanent that he/she is also a man that can commit mistake. Love him unconditonally and dont take him/her for granted as much as many broken relationships do. Be considerate. You should love truly.

should trust each other.put your heart to him or her. Love is something how much you paid not that much you get. but if you don't paid on that,you wil get 0,that's for sure. so ,don't think too much how to keep long relationship. just do your best to love the other side.

To make a relationship last you have to accept your partner who he/she is even his/her faults everything about your partner same with him. I know it's not gonna be easy even pains you have to embrace it. Not asking anything in return. Handling it smoothly and cool cause not all the time is a nice day for both of you. Facing problems together for better and for worst. Making everything simple not complicated. If your afraid don't be in a relationship. If you can't handle it don't. It will come anyway. Take your time. We make our own choices,we make our own life. If you see your friends and witnessed how hard to fall in love your still different from them. Their are still alot of relationship that works out. You have your own life think it that way!
