I know a gal that she is very fond of clubbing / partying. I am
not a clubber but I don't mind to go clubbing with her as if I want
to take care of her. No other "bad" intention as I do love her so
much. However, she refuses and says I will get boring as she sticks
to her gal frd.
She told me she just clubbing and don't bother about other
strangers. I kind of believe her as I got no choice as I can't go
for clubbing with her.
Few times, I know that she didn't go home and she said she staying
at her gal frd home, overnight. I trust her. She also used to get
calls / sms from anonymous, who she met in the pub. But, she can't
remember in the next day when she got drunk in yesterday
night.
Until recently, indirectly, I found out something. She was once
drunk and kissing with her ex-uni frd. I feel really disappointed
and I start to imagine she used to be like that when get drunk
during clubbing. I can't stop my imagination. 
She even got into a trouble that a guy pretends as if her in the
msn that "she" (pretended by that guy) likes one-night-stand. I
helped her to find out that guy (a guy which is her frd and also a
clubber). Finally, that guy stops doing that.
Though she just treats me like a normal frd, I questioned her and
begged her stop from clubbing as I love her so much. But, she
refuses and said she willing to face consequences on her
behaviour.
I love her so much and I kind of "forgive" her again and again and
try to forget what had happening. Somehow, it is too difficult to
be so generosity. What I hope now is she could realise and stop
clubbing one day. Until my patient fading out, perhaps, I will give
up on her.
Hence, to all gals, please stop clubbing as it really bring no good
to you and don't expect you could find a mr-right in clubbing /
partying. No prejudice, but, I don't believe that a person would be
"true" to you under the effect of alcohol and the "high" feeling
when clubbing / partying.
Though it may be right to say that you just go to party for
socializing. But, it would be better not get addicted to clubbing /
partying and most important, not to alcohol.
