I didn't know that it can be so hard

I've never thought that it would hurt so much.

But this is the right thing to do. The differences are just too much.

I knew it all along, lying to myself that we can work things out.

But how could we have worked it out if both of us were not going to change?

In fact, it is wrong to change. If it doesn't fit in the first place, it was not meant to be.
