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.
