Avoiding pain at all cost. What kind of life is that? Does that mean you can't be happy? Do you have to forefit possible happiness because of possible hurt and pain? If you are afraid that you might get hurt while in a relationship then how can you live a normal life? How can you experience all the goodness and badness of life?
Just be cautious and you can still be happy.
Don't avoid falling inlove just because you don't want to get hurt?
