Toxic friend

Imagine you have a toxic friend that is ruining your life.
Oulaya is one of my best friends that i have met, we always fight, but easily se make a solution about the conflicts.
Se have a lot of problems to do something, something important when we are toghether, we spend very good time and we forget that what we have to do.
For example when se make homework or when we stay tighether.
The solution would be for me, that when we do a important task, it was better to separated and make it Alone.
In conclusion, we have a solution but the relation is in crisis.
