Difficulties in relationship

What can a love do? How can you stand when happen different events which make you to cry and be so tired by the situation? You are good and some events just make you nervous and quarrel with your lover. When you expect some things and finally happen others. You try to give strength but you can't because you haven't the strength. And when you start to talk about separation, that moment both of you realize that you can't live separately. Maybe this is the real love.
 Many things in life happen without to like us but they are the difficulties of the life. The same becomes in relationship. You must be strong to stand on your foot. In my opinion only the weak will quit . I talk of course for real loves and big relationships not necessarily in duration but in passion. Because those are relationships which have demands. The others are not serious. When you love someone you give everything to him. You don't let him. You can talk hard  sometimes,  but it is from tension and in some cases it's good because it gives balance in a relationship.
