Struggling With Be Over Nice and Overreacting

Hi Brooke, I have a hard time between being nice with people around or being serious. It is funny since I am really kind and caring person and most of the time I control myself not be over nice since people put all their responsibilities to me. It happened to me many times in my relationship so I decided to get out of the relationship since I found that he is happier than me. On the other hand when I try to not be so kind I will be so serious and disciplined. Either way is annoying for me. Do you have any idea?
