Sometimes we think the defference and talk about it.
One day, I realized the defference or decided my opinion.
I'll tell you right off, but I don't intend to persuade you.
My image of 愛 and 恋 is like the picture below.

Personally speaking, 愛 is broader in scope than 恋.
Objects of our 愛 are various from things to people.
兄弟愛、親子愛、動物愛、植物愛、消しゴム愛・・・
They are love. But sometimes 恋 is born between brothers.ww
If you love something and/or someone, you devote yourself to them.
If the object of our 愛 is an opposite sex, the 愛 may turn to 恋.
This means even if you love someone of the opposite sex, 恋 may not be born.
If you meet a person of the opposite sex, which may make 恋 and the 恋 turns to 愛.
There is no 恋 without 愛.
At the time of 恋, you fall in 愛 at the same time.
恋 is a trigger of 愛
