1. Ann endures an abusive behavior of her friends. They inflict pain her every time.

1, Ann puts up with abusive behaviour from her boyfriends. She gets hurt every time. 

I think from the context 'boyfriend' is required here. 'friend' could be a man or a woman.  To 'inflict pain' makes it sound more physical not emotional. 

2. Ann always clings to her friends, even if they cheat her.

2. Ann always stays with (her) boyfiends, even if they cheat on her. 

3. Eventually she will not so stubborn and find a new decent friend.

3. I'm not sure that 'eventually' is the correct word here. I think 'perhaps' is more appropriate. I suggest this version

3. 'Perhaps she'll change one day and find herself a decent boyfriend instead.'

4. Maybe she can't make accurate choice or maybe she rotates in wrong society.

4. Maybe It's because she makes bad choices or moves in the wrong circles 

5. Frankly, she is not sincere too, so she attracts so-called "trash".

5. To be honest, she is not sincere either, so she attracts 'trash'/ losers. (a good word to use here for a bad boyfiend would be 'loser'

6. She always performs secondary role in any relationships.

6. She is always the submissive partner in her relationships.

7. People treat to her without respect, because she is devoid respect to herself.

7. People disrespect her because she does not respect herself.

8. Regardless she is fabulous creature, she is addicted to strange men such as careless scoundrel or absent-minded bachelor.

8, Even though she is an amazing person, she has lousy taste in men and always goes for the wrong type like players or committment phobes. 

I have tried to work out what you mean by these  negative types of 'strange men' In English we say 'the wrong type'.  'player' is a man who likes to have lots of girlfriends  and 'committment phobe' is for a man who does not want to be in a long term relationship.

9. She can't determine work out/see who is good and who is bad.
10. She is my close friend despite of her traits.
