What's wrong with my daughter?

The relationship with my children is the kind where we talk about everything including their love life.

Two years ago, one of my daughters introduced to me her boyfriend who she dated for about six months before she introduced another gentleman who I got to know was a brother to her boyfriend.  

I was disappointed and reprimanded her and she promised to leave both brothers.

However, in January this year she got involved with a different man who she left for his younger brother again.


I and their father have given our children a good example because we've been in marriage for 25 years. I married my husband still a virgin and feel so disturbed that my daughter is reckless yet I always advise to emulate me.
 

I'm so disappointed and afraid for my daughter's future. Please help me save her before she's completely destroyed.
