You shouldn't marry him if he keeps on showing this signs or attitude.

1.He always yell at you in every slight provocation. 

If he always yell at you in every slightest mistake, that is a red flag for you, a sign he will be beating you as time goes on.

2. He always report you to his mother  whenever you do anything wrong.

If a man always report you to his mum or your mum whenever you do something wrong, or have issues instead of settling it between both of you then it's a red flag for you.

3. He doesn't regard your opinion in any issue.

That is a signal that he would be treating you more like a housemate than a wife when he eventually marries you. 

4. He doesn't give you adequate attention or show proper care whenever you are sick.

That is a sign that he would not be taking good care of you when he eventually marries you.

If he keeps on showing much of this attitude, it's a sign that you should not marry him.
