Is it easy to forgive?

So I had a friend (really a friend)…
She was in love with a guy whom, as usual and as often in India, her parents did not like.
Or I should rather say that they did not like the idea of their daughter finding some one on her own. So they did evrything in their power to stop her from meeting this guy.
At first they tried the strict approach aka “Do not meet this guy because I said so!!!”.
Nothing fights more passionately than a young love just wanting to be, so needless to say the first approach tanked and fell face down.
Than her dad and brother went all Bruce Lee. Knocked some teeth out her pretty mouth.
She had to be admitted in a hospital. She couldn’t come to college for nearly a month. They even threatened to get her boyfriend killed.
But damn that also did not stir her, instead all it did was that it made her more resolute and indifferent to her parent’s pleas and urges.
Then they tried the sure shot approach(works every time) Emotional Blackmail. But alas that also did not work.
So they finally gave in under certain circumstances of course.
Long story short she has to work for two years before getting married to the guy and blah blah blah.
She is living with her family now and has a steady job.
Recently she posted a picture on a Social Media, a happy portrait of her father, brother, mother and herself. So it got me thinking.
Is it that easy to forgive your loved ones when they have been brutal to you in a way that her parents had been to her.
I understand all the concerns that a Parent might have about the guy, but they did not even try to get to know him before giving out the “NO” verdict.
Can you still look at your father the same way after he beat you so bad that you thought you might die.
Can you still tie Rakhi to your brother who tried to get the love of your life killed.
