Help me that i make sentences ~

Did i write these sentences correctly?

There is a man who is my best friend
I like him because he is a man of passion.
For example, he passionately studied when he went to school in the past and now he work passionately from early morning to late night.

He works passionately (He is singular third person, so the verb should end with 's' in simple present. eg He eats noodles. He runs fast. He goes to school)
I like his style and I am getting trust him but sometimes i'm really worried about him because he never enjoy his life, just always work for his future.

He never enjoys his life and always works for his future. (the same mistake as above)
But i think he never work hard for it, maybe he do it all passionately for the people around him.

(I don't really get what you are trying to say here. He is passionate but doesn't work hard??)
These dyas, He falls in love from a woman.

He has fallen in love with a woman recently. (You used simple present tense 'falls' to describe an event which has already occured. Recently is a more apt substitute for 'these days')
Likewise, He loves her passionately.

(You shouldn't use capital 'H' in the middle of the sentence. The comma is unnecessary)
He sacrifices himself for his love and gave her his all things.

He sacrificed himself (better to say he sacrificed his self-interest) and gave away all his things to her.
Sometimes He looks poor and im really afraid this situation because she might leave my friend.

Sometimes he looks poor and I'm really afraid of this situation because she might leave my friend (beacause of his poverty?)
