My ex-boyfriend gave me a letter. Is he a good man?

You are his unforgettable first love, that's all.

He has given up on you. Your night was his last good memory.

It must be because he already has a new girlfriend. But it's a bit confusing to say that you will help unconditionally in the future. This kind of man is a bit indecisive. He won't marry you, making you think he still cares about you.

Maybe he thought it was for your own good and forbeared it, but it was still tied to your heart.

I hope you won't be a mistress in the future.

The past is over, I hope you can have a new beginning.
