Controlling people

I have this hot friend East European shes bubbly talkative affectionate in a friends way but in the company of her boyfriend she is like a different person altogether It broke my heart at the beginning to see her unable to form her own opinion being talked down to been told do this do that never ever gives her a compliment takes her nowhere but now she simply ain't for changing In short he controls her ,hes cool with me going for a coffee with her though but my point is just be on the lookout for such people heres a few warning signs of a controlling person
-Always needs to be right
-tells u who u are & what u think
-Implies that your wrong or inadequate if u dont agree
-doesn't seem to hear or see u
-feels attacked when threatened

don't ruin your life don't let another person control u....
