these days I have been very sad, because a Man broke my heart... I was fall in love, I always accepted that he said, frequently he was rude and he sometimes visited me...

He always told me that he didn't love me very much...but I wanted to be with his...

very sad... my heart is broken

I would not use the word mope or mopey.  This is the kind of word to describe someone who is feeling sorry for himself or herself, but for something that is not very serious.  For instance, a child who has been told he can’t go play outside might mope around the house because he can’t do what he wants to do.

A broken heart is more serious, so you would use a more serious word, in my opinion.

I would edit your writing like this:

My heart is broken

These days I’ve been very sad because a man broke my heart.  I fell in love and I always accepted what he said to me, even though he was frequently rude when he visited.  

He always told me that he didn’t love me very much, but I wanted to be with him.  I’m so sad.  My heart is broken. 

I'm so sorry about this.  I hope you find someone who deserves you.  There is a saying that it's better to be alone than to be in bad company.  I hope you find the truth in that.  Take care.  Your English is very good!  Keep up the good work :-)
