People opt to have a boyfriend-girlfriend relationship because there is a ticket for a way out of the relationship way easily. There is no formal agreement so any party can break it any time however they want to. However, this leads to more implications than benefits, but people fail to perceive it. They bring arguments such as to find a compatible match, marriage is difficult, etc. But, because the marriage system nowadays have been rotten to the core, I am not surprised.
The only solution is to implement the law of Allah, and society will once again bloom. But the further we go from the original way of living, the more we kill ourselves from within.
