He loved her.
He loved her so much his love overflowed onto other women.
He cared about her.
That's why he was so protective.
That's why he got angry when she talked to other men.
He was passionate about her.
It's only natural for passion to turn into anger sometimes.
It's only natural for anger to become physical.
He thought she was beautiful.
Which was the reason he kissed her and ****** her.
Even when she didn't want him to.
He wanted her to be happy.
She couldn't possibly be happy without him.
So he made sure she didn't leave.
He missed her.
So he visited her grave.
But that got tiresome.
So he found someone else to love.
